Synopsis:         Linear Programming using GLPK and comfort-array
Description:
  Simple interface to linear programming functions provided by GLPK
  using the flexible Array shape framework from @comfort-array@.
  .
  E.g. you can use @Shape.Tuple@ to convert safely
  between nested tuples and arrays with the same number of elements.
  .
  > type X = Shape.Element
  > type PairShape = Shape.NestedTuple Shape.TupleIndex (X,X)
  >
  > case Shape.indexTupleFromShape (Shape.static :: PairShape) of
  >   (posIx,negIx) ->
  >     case mapSnd (mapSnd Array.toTuple) <$>
  >          LP.simplex [] [[1.*posIx, (-1).*negIx] ==. 314]
  >            (LP.Minimize,
  >             Array.fromTuple (23,42) :: Array PairShape Double)
  >       of
  >         (Right (LP.Optimal, (absol, (pos, neg)))) ->
  >           printf "absol %f,  pos %f, neg %f\n" absol pos neg
  >         _ -> fail "GLPK solver failed"
