Make _repr_ of MILP more informative

[jdemeyer]

I am solving LP problems where I only care about feasibility and would prefer to see

Linear Program (no objective, 128 variables, 632 constraints)

instead of

Mixed Integer Program  ( maximization, 128 variables, 632 constraints )

Component: user interface

Keywords: days88, IMA coding sprints
