DragoNN code design

We provide two ways to interface with the dragonn package. The interface used in the IPython notebook tutorials is in ./dragonn/tutorial_utils.py, which provides simple wrappers for the dragonn code for simulations of regulatory sequence, model training, and data interpretation. The command-line interface for modeling and interpretation of non-simulated data is in ./dragonn/__main__.py, which provide console entry points for the dragonn train, dragonn test, and dragonn predict commands.
