* Name: nxlooper_create

*
|

* Allocates and Initializes a NxLooper context that is passed to all

* nxlooper routines. The looper MUST be destroyed using the

* nxlooper_destroy() routine since the context is reference counted.
|
||||
* The context can be used in a mode where the caller creates the

* context, starts a looping, and then forgets about the context
|
||||
* and it will self free. This is because the nxlooper_loopraw
|

* will also create a reference to the context, so the client calling

* nxlooper_destroy() won't actually de-allocate anything. The freeing

* Alternately, the caller can create the object and hold on to it, then
