Makefile

# This makefile is borderline spaghetti code/unmaintainable. It works for now,
# with the mere 6 or 7 source files we have at the moment. If we were to
# significantly expand that number, loops would need to be integrated, or even a
# move to automake would be justified. However, at the moment, this is passable,
# and has the desired effect of keeping the code organized and the working
# directory clear of build artifacts.
