/*
 * A command line based tool to run tests.
 * TestRunner expects as its only argument the name of a TestCase class.
 * TestRunner prints out a trace as the tests are executed followed by a
 * summary at the end.
 *
 * You can add to the tests that the TestRunner knows about by 
 * making additional calls to "addTest (...)" in main.
 *
 * Here is the synopsis:
