------------------------


Provide a mechanism for the definition and use of primary keys for cull lists.

Reserve a bit for the flags defining field attributes.

Create the necessary infrastructure for the use of primary keys:
- creation of the underlying hash tables
- use and update of the primary key hash tables in list inserts/removes and object field value updates
- create functions for the search by primary key

Issue 305 has to be done before.
