--
--	Version History
--		001	Initial version.
--		002	Converted to using a hooked function to register completed quests.
--			Made it so quests that never appear in the quest log can be marked completed assuming the quest data is up to date.
--			Condensed the debug statements.
--			Changed the architecture so extra information can be returned for failure conditions.
--			Switched ProfessionExceeds to be able to use localized names of professions.
--		003	Made it so Darkmoon Faire NPCs return the location based on where the Darkmoon Faire currently is.
--			Removed the QUEST_AUTOCOMPLETE event handling since it seems to be unneeded.
--			Added specialZones which allow mapping of GetZoneText() to things we prefer.
--			Removed the check for IsDaily() and IsWeekly() from the Status routine since they are marked as non-complete when reset happens.
--			Added IsYearly() because there are holiday quests that can be completed only once.
--			Resettable quests (daily/weekly/yearly) are now recorded specially so quests can be queried as to whether they have ever been completed using HasQuestEverBeenCompleted().
--			Added a notification system for accepting and completing quests.
--			Added API to get quests that are available during an event (holiday).
--		004	Corrected a problem where resettable quests could not be saved for initial use.
--			Augmented level checking to maximum level is checked as well.
--			Added a targetLevel parameter to filtering quests.
--			Made it so "Near" NPCs can have a specific zone associated with them which makes their return location table entry have the zone name and the word "Near".
--			Removed the need for specialZones since GetRealZoneText() does what we need.  Switched the use of GetZoneText() to GetRealZoneText().
--			ProfessionExceeds() now returns success and skill level, where skill level can be Grail.NO_SKILL if the player does not have that skill at all.
--			LocationNPC() now has more parameters to refine the locations returned.
--			LocationQuest() now makes use of LocationNPC() changes and can return the NPC name as well.
--		005	Quest titles that do not match our internal database are recorded, which helpfully gives us localizations as well.
--			Made it so repeatable quests are also recorded in the resettable quests list.
--			Did a little optimization by declaring some LUA functions local.
--			Made some quest traversal routines take an optional argument to force garbage collection, which greatly increases the time to return the desired data, but brings the footprint back down.
--			Added a routine to get the riding skill level.
--			Made it so QueryQuestsCompleted() is called at startup because the earlier assumption did not take into account that there was still another add-on that did it.
--			Made it so we call QueryQuestsCompleted() if GetQuestResetTime() indicates that quests have been reset.  LIMITATION: The check that triggers this only happens upon accepting or completing a quest.
--			Corrected a problem in ProfessionExceeds() where the comparison was incorrect.  Also made sure the skill exists before API is called.  Changed the value of Grail.NO_SKILL.
--			IsNPCAvailable() now can work with heroic NPCs in their instances.
--		006	Corrected a problem where the questResetTime variable was misspelled.
--			Made it so the SpecialQuests are cleaned out of the GrailDatabase properly.
--			Switched City of Ironforge to Ironforge to match GetRealZoneText() return value.
--			Added a table that contains the quests per zone to allow QuestsInZone() to return the cached information immediately.
--			Made it so a callback can be registered for quest abandoning.
--		007	Corrected a problem where a mismatch in title would cause a LUA error when attempting to record bad quest data.
--			Made it so the GrailDatabase gets its NewQuests and NewNPCs cleaned out properly.
--			Added a QuestName function so the name can be gotten without need for internal data structure knowledge.
--			Added Quest and NPC localizations for French, German, Russian and Spanish.
--		008	Changed hooking quest completing to actually get the current script associated instead of the global name for the script.
--			Corrected some problems where LUA errors would occur if the internal database did not know about a quest.
--			Added support for a quest to have a prerequisite quest in the quest log and not complete.
--			Added support for automatic quests to indicate the NPC that needs to be killed to initiate quest acceptance.
--			Added support for automatic quests that are obtained from entering a zone.
--			Added a zoneMapping table that maps zone IDs returned by GetCurrentMapAreaID() to those used internally.
--			Made it so Status can ignore prerequisite requirements of a quest.
--			Made LocationQuest also return the NPC ID as well as the other information it returns.
--			Restructured the posting of the abandon notification to be about 0.75 seconds after the button click because it seems the quest log does not actually remove it immediately.
--			Added capability to handle indirect items where another NPC drops the one that starts the quest.  The NPC name returned is an NPC that drops the item followed by the item name in parentheses.
--		009	Added more mappings from GetCurrentMapAreaID().
--			Corrected a problem where some parameter names in Status() were not the same as in the implementation, thereby ignoring their values.
--			Added a QuestLevel() function.
--			MeetsRequirementLevel() now returns the levels used to determine success.
--			Added some quest interrogation routines IsEscort(), IsDungeon(), IsRaid(), IsPVP(), IsGroup() and IsHeroic().
--			Added a QuestsInMap() function that uses a map ID.
--			Added a convenience function SingleMapLocationQuest().
--		010	Added an NPCName() function.
--			Added an IsTooltipNPC() which indicates what type of NPC we are dealing with for those that modify tooltips.
--			Added an AvailableBreadcrumbs() which returns breadcrumb quests available to be gotten for the specified quest.
--		011	Corrected an issue where ensuring all prerequisite quests were confirmed could have been inaccurate.
--			Added AncestorStatus() and made Status() call it so prerequisite quests are checked to ensure they can be completed otherwise the Status will be false.  For example, this makes
--			an entire quest chain unavailable if the race does not permit the first quest to be accepted.
--			Debugging has now been turned off by default.
--			A new feature called tracking has been provided to keep a little history of basic quest activity, but is off by default.
--			Changed the posting of abandon notifications to be about 1.0 seconds after the button click since there were times when 0.75 seconds was not enough, and made it a variable.
--			Added some clearing out of BadQuestData that has been added to the database.
--			Made clearing out of NewQuest data more robust.
--			Changed to have NPC locations use map area IDs.
--			Removed the zoneMapping and zones tables as part of the move to using map area IDs for all locations.
--			Made the quest index per map area computed at runtime for the latest most accurate data.
--		012	Made it so marking a quest complete only does so if the quest is not already complete.  This is just a precaution to handle an edge case.
--			Added the "/grail backup" and "/grail compare" commands to help find quest IDs for quests that do not enter the quest log.
--			Made it so special quests that never appear in the quest log can be recorded as complete when there is more than one quest with the same name as long as the NPC ID is different.
--			Made it so NPC locations return the dungeon level and the alias map ID.
--			Added a lot of quest/NPC information for the Midsummer Fire Festival.
--		013	Updated quests and NPCs for Firelands.
--			Did a bunch of localization.
--		014	Corrected some localization issues.
--			Updates quests and NPCs for Mount Hyjal and Firelands.
--			Corrected quest prerequisite information to remove cycles to make a DAG.
--			Added AncestorQuests() which returns a complicated table structure of prerequisite quests.
--		015	Made low level comparisons use Blizzard's own routine so grey quests appear properly.
--			Added more quest level information.
--			Updates to quests/NPCs for Firelands, Alliance Grizzly Hills, and Kezan.
--			Added processing to have holiday quests stored in their own map areas (besides where the quest givers are) so they can be viewed as a group.
--			Added the ability to handle PH: prerequisites that require a quest to have been completed sometime in the past (used with dailies that are triggers).
--			Added the ability to handle Xc codes which exclude classes (basically the opposite of Cc codes).
--		016	Updates to quests/NPCs for Gilneas, and Durotar.
--			Corrected a problem in MultipleUniqueMapLocationQuest() where the accept or turn in parameter was not being passed along properly.
--		017	Updated quest and NPC data to minimize problems with stack overflows, etc.
--			Made it so questgiver locations with NearXXX codes are ignored like Near.
--			Made it so AncestorStatus is now passed the same ignore flags as Status so any subsequent calls to Status will get passed them as well.
--			Added tables for the five continents' dungeons.
--		018	Set up basic structures to start support for ptBR localization when Brazilian version comes on line.
--			Updated a large number of localizations for quest names.

--			Made it so a nil value we sometimes get will no longer crash, but output something helpful.
--		019	Added support for PC: quest codes.
--			Updated some Alliance quest information for Northern Stranglethorn, Cape of Stranglethorn, Dustwallow Marsh, Dun Morogh, Loch Modan, Wetlands, Arathi Highlands, The Hinterlands, Western Plaguelands, Badlands, Searing Gorge, Burning Steppes, Swamp of Sorrows, Darkshore, Teldrassil, Hillsbrad Foothills, Azuremyst, Bloodmyst Isle, Zul'Drak and the capital cities.
--			Updated some quest information for Mulgore, Tirisfal Glades and Silverpine Forest.
--			Made it so AvailableBreadcrumbs() will return breadcrumbs that have prerequisites that can be fulfilled as well as ones that are currently available.
--			K codes for cooking, fishing, and Brewfest quests have been changed to level 0 to indicate the actual level is the same as the player accepting the quest.
--			The zone-specific Self NPCs are now automatically generated for each zone.
--			Changed Status() to return a "Level" failure last of all the checks.
--			Corrected a probem where DEATHKNIGHT was not properly used as the class type.
--			Made it so there is a "map area" that contains all the daily quests.
--			Made "map areas" to contain each of the quests only available to specific classes.

--			Added more support for StatusCode() to support some more bit values plus values from prerequisites.
--			When using StatusCode() quest status values are cached to avoid recomputing values.  The cached values are invalidated as appropriate based on environment and the values of the status.
--			Made IsLowLevel() never consider quests whose level is 0 as low-level since those quests' levels change to match the player level.
--			Removed the Ahn'Qiraj War Effort from the list of world events.
--			Marked Status() as deprecated API which will be removed in the future.
--			Changed the method by which abandoned quests have their notifications posted so the variable abandonedQuestId no longer exists.
--			Added support for LoremasterMapArea() API which provides the map area of the Loremaster achievement for which the quest qualifies.  Also added Grail.loremasterQuests[mapAreaId] tables which list the quests that are used for each Loremaster achievement.

--			Updates some Portuguese localizations.
--			Updates the CleanDatabase() routine to do more cleaning.
--			Makes it so slash commands are not forced to lower case.

--			Fixes a problem where CleanDatabase() could attempt to access data that does not exist.

--
--	Known Issues
--
--			The use of GetQuestResetTime() is not adequate, nor is the API good enough to provide us accurate information for weeklies (and possibly yearlies depending on when they actually reset compared to dailies).
--				The check is only made when a quest is accepted or completed, and this means the reset could happen during play and the Blizzard-provided data would be out of date until a restart or one of our
--				monitored events occurs.  This is the price one pays for not using something like OnUpdate.
--			Support for Neutral faction for starting Pandarens does not exist as it need not.  Quests are marked with a racial requirement, and the system
--				should handle the situation when the Pandaren chooses the desired faction.
--
--			Update the "BadQuestData" data recording/cleaning to handle the rest of the failure possibilities.
--			Need to make it so special quests with the same name AND same NPC ID can be handled.  For the Consortium gem quests I believe we will have to check the levels of the Consortium rep to know how to distinguish.
--			Need a time detection system because we need to know when we cross boundaries for things like the fishing holidays so we can turn the quests on or off appropriately.  This will also allow us to handle other time-based quests.  It means we will most likely use OnUpdate and the above comment will go away and we can actually put in a timer for the next quest reset time so we know when dailies reset.  Of course this means we may want to study the calendar to know when an upcoming event boundary will be crossed as well other than fishing (like Darkmoon Faire, etc.).
--			Need to be able to set Grail.playerFactionBitMask for a Pandaren if they start out playing before they select a faction, and then select a faction during play.  Otherwise they will be defaulted to Alliance which could prove problematic.
--
--			Celebratingholiday() does not check the time when a holiday starts and stops, and assumes presence of a holiday on a day means the entire day has the holiday.  This is incorrect for holidays, that for example, start or end at 02h00.
--
--			Determine if it is possible to notice when a faction is marked "at war" by the user so reputation checks against it take that into account because when one is "at war" the NPCs will not give the quests as expected.  If we can note whether at war then we need to mark NPCs as being associated with a specific faction.  If the NPC has a faction then we can check whether at war (or a low enough reputation with the faction).  Added _NPCFaction() to handle getting the data assuming we have it.

	--	Even though it is documented that UNIT_QUEST_LOG_CHANGED is preferable to QUEST_LOG_UPDATE, in practice UNIT_QUEST_LOG_CHANGED fails
	--	to do what it is supposed to do.  In fact, processing cannot properly happen using it and not QUEST_LOG_UPDATE, even with proper
	--	priming of the data structures.  Therefore, this addon makes use of QUEST_LOG_UPDATE instead.  Actually, this has proven to be a
	--	little unreliable as well, so a hooked function is now used instead.

	--	It would be really convenient to be able not to store the localized names of the quests and the NPCs.  However, the only real way
	--	to get any arbitrary one (that is not in the quest log) is to populate the tooltip with a hyperlink.  However, that will not normally
	--	return results immediately from a server query, so another attempt at tooltip population is needed.  In the case of quests, this
	--	works pretty well.  However, with NPCs the results are less than satisfactory.  In reality, we want the information to be readily
	--	available for when someone needs it, so polling the server is not convenient.  Therefore, we will continue to store the localized
	--	names of these objects so they are available immediately to the caller.  This means the size of the add-on in memory is going to
	--	be constant and not growing overtime if we were to attempt to populate the information in the background (which we would want to do
	--	to make the information available).

	--	Instead of trying to deal with the concept of having NPCs who have unique IDs to be associated with each other but only be available
	--	in specific "phases", the availability of an NPC should probably be checked through the use of determining whether a quest can be
	--	obtained.  Normally, the prerequisite structure of the quests will indicate specific quests cannot yet be obtained, and those are
	--	likely to be associated with the NPCs that will be in new "phases".  Therefore, nothing special needs be done in this library, but
	--	the onus can be put on the user of this library to ensure only quest givers for available quests are listed/shown.

	--	The Blizzard quest log list cannot reliably be queried upon startup until after the PLAYER_ALIVE event has been received.  However,
	--	setting a flag during that event processing will not work since reloading the UI will not cause PLAYER_ALIVE to be sent again, but
	--	will cause the flag to be reset.  It appears under brief testing that QUEST_LOG_UPDATE fires after PLAYER_ALIVE on normal login, and
	--	fires sometime after PLAYER_LOGIN after a UI reload.  Therefore, the flag will be set in QUEST_LOG_UPDATE event processing.

	--	Another issue is the fact that the calendar API cannot be properly used to get real data until OpenCalendar() has returned something
	--	useful, which cannot occur until later in the login sequence.  And trying to call OpenCalendar() without calling CalendarSetAbsMonth()
	--	beforehand makes it so the call does nothing and the CALENDAR_UPDATE_EVENT_LIST event is never sent.

	--
	--	Caching of the quest status.
	--
	--	If the status of a quest is requested, and that status already exists in the cache, then the cache results
	--	should be returned.  When the status of a quest is computed it is added to the quest status cache.  The
	--	cache of a quest status can be invalidated based on what happens in the environment and the status of the
	--	quest.  For example, if a quest was marked as being too high for the player to obtain, but the player gains
	--	a level, that quest status in the cache needs to be removed so it can be recomputed when needed.
	--

	--	For some quests Blizzard marks others complete when you complete one.  For example, Firelands dailies are in groups and when you
	--	finish one, the others are marked complete on the server.  This tends not to be a problem.  However, Blizzard also does this with
	--	quests the player would never be able to acquire, like the starting zone class-specific quests.  So, when a mage completes its
	--	class quest the server marks the class quests for hunter, warrior, etc. also complete.  This seems idiotic as Blizzard already has
	--	other mechanisms to limit a mage from getting a hunter quest, for example.  This causes a problem with the way Grail evaluates the
	--	status of a quest, since it is done "live" because quests have so many relationships.  In general, the quests that one could never
	--	aquire are evaluated such during play, and in the future when they are marked complete on the server they will be both marked
	--	complete since we must believe what the server reports, and will be marked unobtainable for whatever reasons are appropriate.
	--	This works well except for when we attempt to evaluate prerequisites because part of prerequisites is to see if the required quest
	--	is complete.  However, we also check to see whether the quest can be obtained.  The flaw that we currently have is that we are
	--	evaluating whether the quest can be obtained currently, which is technically incorrect because it should be can the quest be
	--	obtained at the time the quest is marked complete.  Of course we can only know this if we keep track of which specific quests are
	--	marked complete when any other is done.  This is yet another level of annoyance that Blizzard causes that it need not.  So, Grail
	--	is going to approximate this for the time being with evaluating the current ability to accept a quest that was complete.

	--	Blizzard seems to have some internal method of determining state with regard to quests that is not flagged using another quest.
	--	They do use other quests sometimes, but not all the time.  Therefore, to ensure we keep a similar state bogus quests are used within
	--	the database, but these are not going to be present from the server query.  Therefore, this state is kept in controlCompletedQuests
	--	which will be checked every time the results from the server query are processed to ensure the internally kept master completed
	--	quests include them.

	--	Database of stored information per character.
	GrailDatabasePlayer = {}
	GrailDatabase = { }
	--	The completedQuests is a table of 32-bit integers.  The index in the table indicates which set of 32 bits are being used and the value at that index
	--	is a bit representation of completed quests in that 32 quest range.  For example, quest 7 being the only one completed in the quests from 1 to 32
	--	would mean table entry 0 would have a value of 64.  Quest 33 being done would mean [1] = 1, while quests 33 and 35 would mean [1] = 5.  The user need
	--	not know any of this since the API to access this information takes care of the dirty work.
	--	The completedResettableQuests is just like completedQuests except it records only those quests that Blizzard resets like dailies and weeklies.  This
	--	is used for API that can determine if a quest has ever been completed (since a daily could have been completed in the past, but Blizzard's API would
	--	indicate that it is currently not completed (because it has been reset)).
	--	There are four possible tables of interest:  NewNPCs, NewQuests, SpecialQuests and BadQuestData.
	--	These tables could be used to provide feedback which can be used to update the internal database to provide more accurate quest information.

		*** Design ***

		Blizzard provides API that details all the quests that their servers record a player as having completed.  However,
		this information does not show the entire picture, and could be misleading.  Therefore, Grail attempts to provide the
		user with a better picture of reality by adjusting and accounting for the Blizzard results.
		
			* Blizzard can record multiple quests as turned in, when one is turned in.  Sometimes this includes quests
				the player could never have completed (because they are class-specific, or from a different faction).
			* There are a class of quests that Blizzard never records as being completed (like truly repeatable ones).
			* Blizzard sometimes uses a FLAG quest to mark a phase change or completion of an event.
			* There are quests that once abandoned are not able to be gotten again, but an associated quest becomes
				available to take its place.  Sometimes there is no FLAG quest for this, and Grail attempts to handle
				this by using false FLAG quests.

		There are many aspects of the games that influence what quests are available to a player.  Some of these aspects are
		reasonably static, like race and faction, while others are more dynamic like level, and reputation levels.  Therefore,
		Grail monitors events to ensure it is aware of changes that influence the availability of quests.

			* Player class
			* Player race
			* Player faction
			* Player level (both level too low and level too high)
			* Player gender
			* Player profession level
			* Player reputation level (both too low and too high)
			* Player having completed achievements
			* Player having a specific buff
			* Player having or not having a specific item
			* Player having turned in or not turned in specific quests
			* Player having completed the requirements for specific quests
			* Player having abandoned specific quests
			* Player having specific quests in the quest log
			* Quests only available during specific holidays (or other events)

		Quests usually have only one NPC that gives the quest and one to which the quest is turned in.  However, there are
		quests that have more than one, including quests that are accepted or turned in without a direct NPC (meaning an
		automatic quest the player handles).  Most NPCs have a fixed position in the world, but some move in small paths.
		There are also NPCs that change positions depending on the phase the player is in.  Sometimes Blizzard changes the
		NPC ID of the NPC when they phase, and other times the NPC ID remains the same.

		Grail has its quest data configured using strings that are reasonably human-readable.  This fixed information is
		converted to numbers that are interpreted as bitfields upon loading.  This is the fixed data.  Each quest also has
		a status that is computed upon request based on the player-specific information in combination with the fixed data.
		This status is also a number to be interpreted as a bitfield where multiple aspects can be set.  Each of these
		numbers only uses 32 bits, even though the numbers may be able to hold more bits.

		Since the status of a quest may be somewhat expensive in computing because a quest's prerequisites may need to be
		computed, the status of each quest is only computed upon demand.  And once the status of a quest is computed it is
		cached so future requests do not recompute it.  This means Grail needs to understand what influences the status of
		a quest and therefore monitors those influences for changes.  When changes occurs, it invalidates the cached status
		of the quests and posts a notification to its observers indicating a quest status change.  Clients can then update
		their UIs to reflect the changes in quest statuses.

		The Blizzard API that is used to determine quest status varies and covers quite a few different types of API.  Each
		of these API does not return valid results until certain parts of the Blizzard system have been initialized, so
		Grail needs to ensure it does not rely on results from any of these API until certain events have occurred.  In fact,
		some of the information Blizzard returns needs to be queried after delays because Blizzard systems do not update
		immediately after events or expected UI interactions like pressing buttons.  Grail attempts to handle these by
		setting up a delayed system where it processed things after a time period has passed.

		The internal method that is used to indicate that quests are incompatible with each others works only when there is
		one quest from the group allowed at the same time.  However, there are cases where there are more than one allowed
		from a specific set, like the Anglers dailes for example.  For the Anglers, three of 14 quests are made available
		each day.  A player can still hold a quest from a previous day and if it is not one of the random quests for the
		day, three will be acceptable.  If a held quest is the same as one offered today, the total number of quests on the
		day will be reduced.  Therefore, Grail groups quests together that can have more and one from that set available at
		a time.  The group specifies how many are allowed from the set.  There are very few groups of quests, and so far
		they have all been dailies.
