/**
 *  This class serves as a bridge between the Wily JUnit-style tests and the
 *  Sun test framework.
 *
 *  This is a replacement for the JUnit TestCase base class. Provides surrogate
 *  functionality for the setup/teardown calls, and for all the verification and
 *  assertion services.
 *
 *  The Sun framework relies on each test case being a separate class with a separate main,
 *  which throws if the test fails and does not throw if the test succeeds.
