Refactored classifier.
Did various refactoring of functions, added main and argparsing.
Added joblib support.
Added check for number of processors.
Added documentation.
Input now is data directory and regex for files for multi-file processing.  Default is data.npy and labels.npy
Perhaps include an option to let the input be a data file?
Output now a directory as it now stores the pkl files for each classifier (make this optional in the future?)
Fixed a small typo on last commit.
