packaging the sim

[belgiumkansas]

propose making cairo_sim into a sub-package called core_sim and as separate sub-packages the openai_env and planing.
Thus making cairo_sim the top level package name and allowing for uploading of project to the python packaging index
ie.

from cairo_sim.core_sim.simulator import Simulator
from cairo_sim.planner.collision import self_collision_test

it makes things more verbose but also more flexible to expanding and organizing features. looking for thoughts

This could fairly easily be done with namespacing and as is the import calls are as you've written. I don't really see much motivation to upload to PyPI at the moment? The sim, planner, and openai stuff will be in seriously flux for the next few months.

I propose we bring it up in a month's time to see where we stand? Thoughts?

Yea we can do that. sounds good.
