Initial Development Release

This intitial development release follows a peer review by past ENGRI 1101
students. The bugs they identified are all addressed. This release contains
the core functionality of the gilp (Geometric Interpretation of Linear
Programming) package. Using the simplex.py module, one can create and solve
standard inequality form LPs using the revised simplex method. In addition,
the feasible region of an LP and the iterations of simplex on a given LP
can be visualized using the visualize.py module. Some example LPs are given
in the examples.py module and helper functions for interacting with ploty are
given in the style.py module.
