Untested/incorrectly implemeted dominating set `compute` functions

[joshyaffee]

I've looked into all of the untested Dominating Set compute functions and organized what I came up with here in this Google Doc.

TL;DR:

• MIDS and MPDS lgtm and just need testing and documentation.
• MPDS doesn’t look correct, and I’ve identified a BIP that would work. I will implement the BIP soon.
• MLDS seems like the implementation is wrong and I’ve come up with a BIP that should work, but it is ridiculous. Maybe I’m missing some intuition here. Could you help me with this one @RandyRDavila ?

@joshyaffee My MLDS surely isn't correct. That was one of two I remember correctly that I added as placeholders without docstrings or anything. I'll look into the formulation you have today. Could you find any literature implementing a BIP for it?

The closest I could find was a paper that proved that it was NP-Hard to create a speicific type of approximation for it
