+//!from allocating raw memory, the user can construct named objects. To 
+//!achieve this, this class uses the reserved space provided by the allocation
+//!algorithm to place a named_allocator_algo, who takes care of name mappings.
+//!The class can be customized with the char type used for object names
+//!and the memory allocation algorithm to be used.*/
