// This F# dojo is directly inspired by the 
// Digit Recognizer competition from Kaggle.com:
// http://www.kaggle.com/c/digit-recognizer
// The datasets below are simply shorter versions of
// the training dataset from Kaggle.
 
// The goal of the dojo will be to
// create a classifier that uses training data
// to recognize hand-written digits, and
// evaluate the quality of our classifier

# in ruby, nil is an instance of NilClass. we're monkeypatching NilClass at this point, which is a bad idea for a production app. 
# but for this example, it gets the point across and should help you find a solution to what you want... maybe...
