OpenAI Gym Breakout environment

The Breakout-v0 environment allows us to play the classic Atari game Breakout using the OpenAI gym interface.

Relevant information about the environment:

>>> import gym
>>> env = gym.make('Breakout-v0')
>>> env.observation_space
Box(210, 160, 3)
>>> env.action_space
Discrete(4)
>>> env.unwrapped.get_action_meanings()
['NOOP', 'FIRE', 'RIGHT', 'LEFT']

This tells us that the environment is 210 x 160 pixels with 3 color channels, and that we can take one of four actions in the environment at any given point in time: NOOP, FIRE, RIGHT, or LEFT.
