Added methods to cross-validate parameters for feature functions
Added results of TSVD experiments
Merge branch 'casey'

Conflicts:
	ClassifyMalware/classification_starter.py
	ClassifyMalware/mainTestIter.py

Merged my changes. Notably changed the way feature functions are specified
to mainTestIter (can now be passed as array of strings in the params dict()).
I kept the defaults such that the behavior of Sam's code should be unchanged.
