// NOTE:
// Some of these tests are designed to fail! Do not be alarmed.
//                         ----------------

// The following tests are a bit hacky. Whilst Kent Beck tried to
// build a unit tester with a unit tester, I am not that brave.
// Instead I have just hacked together odd test scripts until
// I have enough of a tester to procede more formally.
//
// The proper tests start in all_tests.php
