 Results should be ints in an array, each result accoring to the list of features it should represent the classification of.
 
-### Plan for classifier.py

-Make a command line utility that reads in samples, transforms them to FeatureVectors and then runs a number of
-classifications on them.
+Usage: nearestneighbors.py datafile.bin classificationsfile.bin testdatafile.bin

+A command line utility that reads in FeatureVectors and runs a KNN classification on them.

+Plan for classifier.py:
+Discuss data formatting at meeting, expand utility to include choice of classification and
+make more robust in general
