I'm not quite able to run the code (too much load on the server probably). But is this something that can solve LPs in the browser (possibly more than just LPs, I think)? This would be incredibly helpful for many people I'm sure--all the existing online ones have arcane input reqs (and unhelpful errors) and standalone applications either cost money (Gurobi, cplex) or are not easy to use at all (gnu glpk).
