I've been using the linear programming for class, and love it! Thanks! I
noticed a few areas that would make it more user-friendly:
* it would be great if `p.get_variables()` returned the values of all of
the variables by default, instead of insisting that you ask for a specific
variable
* Maybe a `p.show_solution()` method could be added that would print out
the optimal objective function value and the values of all variables, if
the problem was solved.
* it would be cool if we wrapped the sensitivity analysis of various
solvers. Like
http://en.wikibooks.org/wiki/GLPK/Solution_information#Sensitivity_analysis_report
for GLPK.
* the `maximization=False` parameter is a little awkward. Perhaps that
parameter could be renamed to `type="maximize"` or `type="minimize"`. Or
perhaps we could also have a `minimize=None` parameter, and if maximize
and minimize are both None, the default is maximize (for compatibility),
but if either is set, that is the problem, and if both are set to True,
then we throw an error.
