Parse job files

[StevenMHernandez]

Once we have determined the job file structure, we will need a way to parse these files programmatically.

So in general, we will read any metadata about the program; store that, then read each line of the actual program into a Queue of Strings.

TODO: load files directly from /programs directory. Assume everything has a .txt extension.

so exe paint opens file ../programs/paint.txt or whatever the actual path is.
