	What the different callbacks do:

	AuraHandler: Specific aura tracking needed for this class, who has Beacon up on them and such

	ResetChargeData: Due to spell "queuing" you can't always rely on aura data for buffs that last one or two casts, for example Divine Favor (+100% crit, one spell)
	if you cast Holy Light and queue Flash of Light the library would still see they have Divine Favor and give them crits on both spells. The reset means that the flag that indicates
	they have the aura can be killed and if they interrupt the cast then it will call this and let you reset the flags.

	What happens in terms of what the client thinks and what actually is, is something like this:

	UNIT_SPELLCAST_START, Holy Light -> Divine Favor up
	UNIT_SPELLCAST_SUCCEEDED, Holy Light -> Divine Favor up (But it was really used)
	UNIT_SPELLCAST_START, Flash of Light -> Divine Favor up (It's not actually up but auras didn't update)
	UNIT_AURA -> Divine Favor up (Split second where it still thinks it's up)
	UNIT_AURA -> Divine Favor faded (Client catches up and realizes it's down)

	CalculateHealing: Calculates the healing value, does all the formula calculations talent modifiers and such

	CalculateHotHealing: Used specifically for calculating the heals of hots

	GetHealTargets: Who the heal is going to hit, used for setting extra targets for Beacon of Light + Paladin heal or Prayer of Healing.
	The returns should either be:

	"compressedGUID1,compressedGUID2,compressedGUID3,compressedGUID4", healthAmount
	Or if you need to set specific healing values for one GUID it should be
	"compressedGUID1,healthAmount1,compressedGUID2,healAmount2,compressedGUID3,healAmount3", -1

	The latter is for cases like Glyph of Healing Wave where you need a heal for 1,000 on A and a heal for 200 on the player for B without sending 2 events.
	The -1 tells the library to look in the GUId list for the heal amounts

	**NOTE** Any GUID returned from GetHealTargets must be compressed through a call to compressGUID[guid]
