-- Task Class
------------------------------------------------------------------------------------------------------
-- NewTask(func, ...)   returns a new object, and creates the coroutine with given func and variables
--  .ChangeVars(...)    Change vars to new vars for next .Execute()
--  .SetRepeat(boolean) Sets repeat status to true or false.  If repeat, when the task ends, it restarts.
--  .GetRepeat()    returns if Repeat is set to true or false.
--  .Create()       creates the task, but is not running yet.
--  .Start()        creates if not already created and at the start, then sets the task to Run.
--  .Stop()         stops and finishes the task.  It cannot be resumed.
--  .IsCreated()    checks if the Task's coroutine exists (self._Co ~= nil)
--  .IsRunning()    checks if the Task's is created, if it is running, and not dead (finished running)
--  .IsAtStart()    checks if the Task is created but has not yet run.
--  .IsAtEnd()      checks if the Task has completed, and still exists.
--  .GetStatus()    returns the status of the coroutine, or nil if it doesn't exist
--  .Pause()        stops running the task, but does not destroy it.
--  .Resume()       resumes the task where it left off.
--  .Execute()      run the Task with the given variables.  This should be run every event to keep the task running
--  .Destroy()      stops and removes the Task.  It remove from the TaskHandler and nilled.
--  .Remove()       calls .Destroy()
-- TaskSleep(delay) This will yield within a Task function with the given delay.  Execution will pick up where it left off after the delay.
