 *  A singleton class used to track each of the databases that the
 *      ODBCTapeStream objects are connecting to.  Provides both
 *      dictionary and observer functionality for ODBC connections.
 *  The dictionary ops allow re-use of an existing connection.
 *  The observer routines will hypothetically clean the objects and
 *      gracefully kill the app if a database connection is lost when
 *      I/O is needed.
