A Database to store the unique 'singular' instances of a single object type.
The instances are stored as weak pointers. So the DB does not own these objects, they are owned by object in the client_db.

Find or add the object to the store.
The object passed is deisred state. A new instance will be copy constructed from it. This function is templatised on the object type passed, which may be drrived from, the object type stored. this prevents slicing during the make_shared construction.
