---------------------------+----------------------------
CyLP is a Cython interface to COIN-OR’s Linear and mixed-integer program
solvers (CLP, CBC, and CGL).
We should add a MILP backend that goes through CyLP, because the interface
is much more complete than Sage's current COIN interface. In particular,
quoting from CyLP's README:
"CyLP’s unique feature is that you can use it to alter the solution
process of the solvers from within Python. For example, you may define cut
generators, branch-and-bound strategies, and primal/dual Simplex pivot
rules completely in Python."

Of course, CyLP has an incompatible license (CPL), but it does not matter
because COIN has that license already.
