Title: Fix for issue #13 (lots of ruby warnings generated).

Many of TTFunk's classes had unused variable assignments. The warnings were bothering me, so I changed all unused variables to underscores, but left a comment above the change outlining what the variable represents. All tests pass for me and the warnings are no longer generated.
