stripped-down MCCS CUDF solver for OCaml

 mccs (which stands for Multi Criteria CUDF Solver) is a CUDF problem solver
 developed at UNS during the European MANCOOSI project.
 .
 This repository contains a stripped-down version of the mccs solver, taken from
 snapshot 1.1, with a binding as an OCaml library, and building with dune.
 .
 The binding enables interoperation with binary CUDF data from the OCaml CUDF
 library, and removes the native C++ parsers and printers from mccs.
 Only the GLPK backend and the lpsolve interface are compiled
