RPN FOR NUMWORKS

[Jean-Baptiste Boric]

I'll fill in some details in English about my app.

With the recent improvements, this app is now a 16-level stack RPN frontend to poincare, NumWorks's math engine. It can handle almost any mathematical operation available on the keyboard, but I haven't implemented the toolbox yet to access the more advanced operations. Stack operations are implemented (DUP, OVER, SWAP, ROT) as well as picking by scrolling through the stack. There's room for improvements, but it should be good enough for everyday usage.

This is a third-party app in source code form, so to use it one needs to compile epsilon with the RPN app. I've left a precompiled beta firmware image on TI-Planet for people to try out on their calculators.
