[Cmpl] Convert GMPL to CMPL

[Mike Steglich]

Hi Rob,

Thank you for beeing interested in Cmpl.

I would create a parameter vector Rp defined over the set Products which contains sets of rolls (sub sets of Rolls) that can be used for the product p.

{ p in Products :  Rp[p]:= set { r in Rolls, pWidth[p] <= rWidth[r]: r} ; }

I could not test it because I'm off and writing this on my pad.

Thanks,

Mike
