+// Disclaimer: What we do here isn't real unit testing.  It is a reasonable compromise where we accept the
+//	codebase mostly as is without major refactors and run reasonably small tests that sorta look like unit
+//	tests but are really integration tests.  The key compromise here is that we create a global execution
+//  environment that all the tests share and run within.  This environment dictates what tests are allowed
+//  to do and what shared functionality they have access to.
