Chart Version 5 Changes

Some optimizations were completed.
- Theoretical portion runs faster.
- Chart presentation cleaned up.
- Generalized Directory Specification implemented (done by Bill Mills).
This means users do not have to adjust the directory locations within
the code. Tested and worked on a Windows 7 machine and a Unix machine.

Next Goals
- Implement a Color Bar Scheme option for the Theoretical portion.
- Address any further problems with Chart presentation.
- Make it possible for users to upload their own data text files to use
with this program.
