                     The Production (SP) Parser 

   Init_parser() should be called at startup time.  Parse_production()
   reads an SP (starting from the production name), builds a production,
   adds it to the rete, and returns a pointer to the new production
   (or NIL if any error occurred).  Parse_lhs() reads just an LHS,
   and returns a condition list (or NIL if an error occurred).  
   Parse_rhs() reads an RHS, setting "dest_rhs" to point to the resulting
   action list; it returns TRUE if successful, FALSE if any error occurred.
