* Orthodox performs a simple set of tests on an arbitary
* class to make sure that it supports at least the
* following operations:
*
* default construction - constructor
* equality/inequality - operator== && operator!=
* assignment - operator=
* negation - operator!
* safe passage - copy construction
*
* If operations for each of these are not declared
* the template will not instantiate. If it does
* instantiate, tests are performed to make sure
* that the operations have correct semantics.
*
* Adding an orthodox test to a suite is very
* easy:
*
* public: Test *suite () {
* TestSuite *suiteOfTests = new TestSuite;
* suiteOfTests->addTest (new ComplexNumberTest ("testAdd");
* suiteOfTests->addTest (new TestCaller<Orthodox<Complex> > ());
* return suiteOfTests;
* }
*
* Templated test cases be very useful when you are want to
* make sure that a group of classes have the same form.
*
* see TestSuite
