/**
|

* @brief An Actor pointer that unregisters itself when it goes out of
|
||||
* scope
|
||||
*
|
||||
* This class allows for simple functionality of automatically registering
|
||||
* and unregistering an actor from the manager. Its primary use case is the
|
||||
* ActorAsset, that shares ownership with the manager. But it can also be
|
||||
* used anywhere that needs to make an Actor that needs to be in the
|
||||
* Manager for a given period of time. A good example of this is anything
|
||||
* that needs Actor commands to work on an actor that is made in a given
|
||||
* scope. One main place where this happens is in the Actor asset processor
|
||||
* code.
