Hi. Thanks for the PR! So ideally we wrap all sim.py calls in the higher level api (the user shouldn't be calling sim.py). In this case, I guess it belongs in object.py. Once that's done, there needs to be a test for this. See here: https://github.com/stepjam/PyRep/blob/master/tests/test_objects.py

Yes, I can put it in object.py and add test code

Could you review this PR, please? I think contact info is quite important for a robot to learn from the environment.
