Update Progress

An update is currently in progress with the following changes/additions:

* Arrays have been implemented and are currently being tested.
* Fixed design flaw where -1^2 would evaluate as (-1)^2. The order of operations has been corrected.
* The engine now uses exception handling for errors in processing scripts.
* Functions do not need parenthesis to be called, if they take no arguments.
* Some improvements to macros which extend C++ objects.

Hopefully, I will finish testing these new changes and have some sample scripts written to release this weekend.
