//   RBBISetTableEl   is an entry in the hash table of UnicodeSets that have
//                    been encountered.  The val Node will be of nodetype uset
//                    and contain pointers to the actual UnicodeSets.
//                    The Key is the source string for initializing the set.
//
//                    The hash table is used to avoid creating duplicate
//                    unnamed (not $var references) UnicodeSets.
//

//                       The Hash Table owns these RBBISetTableEl structs and
//                            the key strings.  It does NOT own the val nodes.
