  Added linkage RDB to RDB::MakeTables for SQL_SELECTS, SQL_HEADERS
  Removed constants in RDB.pm
  Removed dbix_ tables and related routines for DBIx::Sequence in RDB::PopulateTables
  Changed mtn, no longer calls normalize in RDB.pm
  Replaced get_xml_name with get_real_element_names_db in RDB.pm
