Notes:
	Fire an event that any tags, handlers, or callbacks will see.
Arguments:
	string - name of the event
	tuple - a tuple of arguments
Example:
	LibStub("LibDogTag-3.0"):FireEvent("MyEvent", "Data", "goes", "here", 52)
]]
function DogTag:FireEvent(event, ...)
	OnEvent(frame, event, ...)

Notes:
	Register a function to be called roughly every 0.05 seconds
	This should only be called by sublibraries
Arguments:
	string - the namespace to mark ownership with
	function - the function to be called
	[optional] number - a number from 1 to 9 specifying the priority it will be called compared to other timers. 1 being called first and 9 being called last. Is 5 by default.
Example:
	LibStub("LibDogTag-3.0"):AddTimerHandler("MyNamespace", function(num, currentTime)
