Project 1 implementation

A couple of notes for your Project 1 Implementation.

1. The name of your class should not literally be NameBanker, but 'your-team-name'Banker, e.g. ChristosBanker. This way I can test all of them later without name-clashes.

2. Make sure your code runs on TestLending.py, and that you do all your hyperparameter tuning in your .fit() function.
