[Numeric] Announcement: Fast linear programming with highs-lp

[Henning Thielemann]

Eventually I have also written a basic wrapper to the relatively new 
linear programming solver HiGHS based on the comfort-array types:
   https://hackage.haskell.org/package/highs-lp

Warm start of the solver is supported by a monadic interface.

The QuickCheck tests in coinor-clp and highs-lp already revealed several 
issues, that are now fixed in the latest commits, that is, 
COIN-OR/Clp:master and HiGHS:latest.

Here is a Nix file for building the currently latest HiGHS commit:

For building master/HEAD of COIN-OR/Clp, you may find these Nix files
