 *
 * PURPOSE:
 * test rasj class RasPoint.
 *
 *
 * COMMENTS:
 * - testing philosophy is to run all tests and report. no exit code / exception
 *   is used for error indication; look into the output for ERROR_TAG instead.
 * - unexpected exceptions are not caught, hence will make gmake fail and show the error
 * - every test that fails must print a line containing ERROR_TAG
 * </pre>
