> There are lots of test problems for linear programming in the MPS format. We should add
a parser for this format to test our SimplexSolver implementation with these problems and
compare with other solvers.
> The parser could be added also to the -tools jar as it might be of interest for users
to load and execute such problems.
> Format: http://lpsolve.sourceforge.net/5.5/mps-format.htm
> Data Files: http://www.netlib.org/lp/data/
