Adding Project Writeup and Sample Program File

Project Write up has been added.  This file is the very very rough
edition of the commands that this sandbox will support.  Additionally a
sample program, 'data.in', file has been added.  This file is currently
being used to test the functionality of the sandbox.
Implemented much of the try_parse functionality.

I have implemented much of the functionality of the try_parse function,
and began designing out the general functionality of the sandbox.
