-- This also includes spells that usually don't have a castbar like Multi-Shot and Aimed Shot.

-- libcast:GetCastInfo(unit)
|

-- Returns all ongoing casts of a unit (name)
|

-- cast, start, casttime, icon, delay, channel

--
|
||||
-- libcast:RegisterEventFunc(func, frame)
|
||||
-- Triggers the given function `func` with `frame` as arg1,
|
||||
-- whenever a new cast-event was detected
|

--
|
||||
-- libcast:TriggerEvents()
|
||||
-- Triggers all registered event functions.
|

--
|
||||
-- libcast:AddAction(mob, spell, channel)
|
||||
-- Adds a spell to the database by using pfUI's spell database
|
||||
-- to obtain durations and icons

-- libcast:RemoveAction(mob, spell)

-- Removes the castbar of a given mob, if `spell` is an interrupt.
