Return top 3 predictions in Codenet Language Classifier model

[ckadner]

@kmh4321 -- I thought we had decided to print the first 3 highest predictions, if there are more than one? When I run the prediction on a Python script I get 85% match for Haskel. It would be interesting to see the next best prediction.
