XP_MAC: no longer auto close upon exit (so we can see asserts, etc.). Renamed testInterpreter() to testFactorial(). Added testObjects(), which allocates an object, stores it in the global variable "global", assigns 0.0 to "global.counter", and finally defines a function "increment" which adds 1.0 to "global.counter" each time it is called.
