* Memory object container access controller.

|
|
* Memory manager stores a list of generated objects to control them.
|
|
* So container objects always have at least one reference and can't be automatically destroyed.
|
|
*
|
|
* This class is intended to be an userland proxy to memory container object.
|

* It's not referenced by memory manager and class destructor is invoked immidiately after gouing
|

* out of scope or unset operation.
|
|
*
|
|
* Class also provides Zend_Memory_Container_Interface interface and works as proxy for such cases.
