A class to hold memory pointers referenced by string names.
This is used to form a typeless data pointer that can be associated and referenced by string/logical name. The memory used for forming the string names can itself be managed in reusable memory pools and the entire structure uses it's own private pager heap. This allows new string named pointers to be added and deleted at runtime in a thread- safe manner. This might typically be used as a session id manager or for symbol tables.
