class TAwaitableTask

Awaitable Tasks are very simple they only allow for Lauching and Awaiting a Task. They will try to run other work while awaiting the Result.

	Type	Name	Description
		TAwaitableTask ()
		TAwaitableTask ( const ThisClass& Other )
		TAwaitableTask ( ThisClass&& Other )

	Type	Name	Description
		~TAwaitableTask ()

Type	Name	Description
ReturnType	Await ()	Await the Task Completion and get the result, this will assert if this is a Dummy Handle.
void	BusyWaitUntilLaunched ()	Busy wait until the Task is launched from another Thread, this can be useful if we want to build chained tasks.
void	Init ( const TCHAR* DebugName, LowLevelTasks::ETaskPriority Priority, CallableT&& Callable )	Initialize a new Task with given Priority now and Abandon previous work (if any) initialized Tasks can be awaited on, but they will run synchronous in this case
void	Init ( const TCHAR* DebugName, CallableT&& Callable )	Initialize a new Task now and Abandon previous work (if any) initialized Tasks can be awaited on, but they will run synchronous in this case
bool	InitAndLaunch ( const TCHAR* DebugName, CallableT&& Callable )	Initialize and Launch a Task
bool	InitAndLaunch ( const TCHAR* DebugName, LowLevelTasks::ETaskPriority Priority, CallableT&& Callable )	Initialize and Launch a Task with given Priority
bool	IsCompleted ()	Returns true if the Tasks completed.
bool	IsLaunched ()	Returns true if the Task has been Launched.
bool	IsValid ()	Does the TaskHandle hold a valid or Dummy Task?
void	Reset ()	Abandon the Task and freeing its memory if this is the last reference to it.
bool	TryLaunch ()	Launches the Task for processing on a WorkerThread. The returntype will specify if the Task was Launched successfully (true) or if it might have been launched already (false)
