Detailed Description
Purpose: Basic class for memory allocation wizards. Defines the interface for devising different allocators firstly to be used by collections of NCollection, though it it is not deferred. It allocates/frees the memory through Standard procedures, thus it is unnecessary (and sometimes injurious) to have more than one such allocator. To avoid creation of multiple objects the constructors were maid inaccessible. To create the BaseAllocator use the method CommonBaseAllocator. Note that this object is managed by Handle.
