* @class ReferencedObject
* @brief Reference counted base class.
*
* ReferencedObject is a reference counting base class.
* it has an integer reference counter so that dynamic objects
* can have their memory allocation handled by the scim
* smart pointer: Pointer<>. This keeps the memory management
* in scim consistent across all classes.
* If you derive a class from ReferencedObject and allocate it
* on the heap, you free the memory and destroy the object by
* calling unref(), not delete.
