Simple .gz file reading

Reads in .gz files. Prints out each line in the file. Doesn't do much
else yet.

Added a test.txt.gz file that is much shorter (the file he gave us has
7, 411, 442 lines to process (which takes about 7 minutes for my desktop
to process)). My test file only has 60 lines, which should make doing
basic debugging a little easier.
