 * Interface for CUnit internal testing functions.
 * Because the CUnit framework cannot be modified during a test
 * run, CUnit cannot be used directly to test itself.  That is,
 * individual functions could set up and initiate CUnit test runs,
 * but the functions themselves cannot be run as CUnit test functions.
 * <br><br>
 * The approach taken here is to set up a mimimal test framework to
 * keep track of logical tests.  The various unit test functions are
 * then free to use the CUnit framework as needed.
