Command Line Enhancements

[wdkaye]

We would like to have just one executable, which can run in a variety of modes

• Sequential

• Parallel

• with one file

• with many files

• encrypt and decrypt modes (if there's time)

• [ ] Design command line flags

• [ ] Implement command line flags

Sequential/Parallel done. Still TODO:

• Several files
• Decrypt mode
• (optional) change to verbosity (for printf output, timing output, etc)
