Encapsulate the GnuPlotter object in a file
Implement GnuPlotter case class

This will hold several default values that will be useful for easy
plotting.
Cleaner column plotting
Silence output
Mapping/zipping Ranges and Lists
Correctly producing the list of plot commands
Use functional results in gnuplot script creation

After getting the initial zipping and mapping set up, I also used reduce
in a neat little way to get my list of plot commands flattened into one
string with a newline separating each entry. I'm really starting to
appreciate how these things can be used.
Cleanup
Remove pointless map call

I thought it was doing some sort of necessary evaluating, but really it
was just a pointless step.
Remove unnecessary toList call

Also realized that my toList call was superfluous! I'm seeing more and
more how terse you can be with this functional stuff.
Break ground on Personal scala library

Move DataWriter and Utility objects to this new library.
Cleanup scattered discarded code chunks
