API:

• add function polytope.polytope.enumerate_integral_points()
• always recompute the volume when calling the function polytope.polytope.volume()
• add parameters nsamples, seed to function polytope.polytope.volume()
• replace certain assert statements with raise statements, raising ValueError or AssertionError

• customizable plotting in methods Polytope.plot and Region.plot

• rename method to Polytope.contains, was are_inside
• add method contains to Region
• deprecate function polytope.is_inside,
  use in and contains instead
• add arg solver to function lpsolve

• PEP440-compliant version identifier vX.Y.Z.dev0+commithash
• test on Travis CI

This initial release has very few changes since its break from TuLiP,
and is primarily intended to provide a reference version that easily integrates
with legacy code developed assuming polytope is a part of TuLiP.
