Erwin Coumans 21f9d1b816 refactor pybullet/gym to allow instantiating environments directly from a pybullet install:
work-in-progress (need to add missing data files, fix paths etc)

example:

pip install pybullet
pip install gym

python
import gym
import pybullet
import pybullet_envs
env = gym.make("HumanoidBulletEnv-v0")
