Tests for recent note extraction are passing.
Added function for padding, but haven't tested yet.
Padding seems to be functional.
Starting work on another counting function. TESTS: what I'm currently doing...
Wrote tests and doc for chord counting function.
Improved doc for chord counting function.
Rough implementation, still throwing test errors.

And... added check to see if new function also works in backwards fashion.
