Python implementations of several robotic motion planners

get_nth() in Lattice.py is not right?

Currently, it has def get_nth(generator, n=0): return next(islice(generator, n), None)

When it should be?:
def get_nth(generator, n=0): return next(islice(generator, n, None))

pip install pybullet_planning error with Ghalton

Hi, just trying to install pybullet_planning and get a feel for the toolkit as per the readocs but I keep running into the following when I execute pip install pybullet_planning.

I noticed that this is an open issue with Ghalton on their page (fmder/ghalton#16) and was wondering if anyone else has run into this issue? I've attempted to follow the suggestions on this link but no luck so far :(.
