Dealing with multiple optimal solution issue #10

Hi all. I remember there was a gitter discussion about the multiple optimal solutions of MCLP and LSCP, and I might have missed some important points on gitter.

How is this issue addressed in the current release of spopt? If there are multiple optimal solutions, will the function output all solutions, or randomly select and output one of them?

We discussed that, but didn't get around to implementing it. It is important that we keep this on the radar though. @gegen07 can you transfer this issue into the spopt repo?

One initial thought is if solvers actually report multiple optimal solutions when they exist, as they absolutely could in the LSCP, MCLP, and p-center.
