+/**
+Indexed storage for server sdide objects.
+
+RDbObjContainer container is used for storing IPC stream handles (HIpcStream) and 
+statement handles (CSqlSrvStatement).
+
+Behaviour when the container is destroyed:
+ - all objects inside the container are destroyed too;
+ 
+Behaviour when the an object is removed from the container:
+ - the container will destroy the object;
+
+Behaviour when the an object is added to the container:
+ - the container stores the object <by_ref>, not <by_val>;
+
+Behaviour when a look up is performed in the container for an object:
+ - a pointer to the object is returned or NULL if there is no object;
