New description:
I propose to extend the interactive_simplex_method classes so that they
take an optional keyword argument "style", which controls several aspects
of how the problems and their dictionaries are presented. The style can
also be set globally.
For example, if style='Vanderbei' (which we are working on in this
ticket), it would follow Robert Vanderbei's popular text. Compared to the
current code (which textbook does it follow?), there are differences in
the naming of slack variables, of the objective functions, and some subtle
formatting differences.
Supporting the styles of some popular textbooks may help making Sage the
tool of choice for teaching the simplex method.
