 * 02-19-2001 GS Created
 *
 * 02-19-2001 GS Ready for testing
 *
 * 02-23-2001 GS added byte to boolean convertion methods for patch library
 *
 * 06-18-2001 GS Fixed possible error in indexOf() methods.
 *
 * 06-21-2001 GS Fixed bug in indexOf() method. Values seemed to be
 *               offset by one so -1 was inserted in many conditional
 *               statements.
 *
 * 07-01-2001 GS Fixed bug in indexOf() method that cause an infinite
 *               loop while searching.
