 /**
  * 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.
