/**

* Referencer<T>
|
||||
* Referencer is an object that holds a reference holder that hold a reference
|
||||
* counted object. When an object's reference count drop to zero, it removes
|
||||
* the object. This is a non intrusive mechanism and any object at any point
|
||||
* in time can be referenced. When and object is reference counted, do not
|
||||
* pass the object directly to other methods but rather, pass its
|
||||
* reference around. Objects can be reference counted in both single threaded
|
||||
* model and multi-threaded model
