[Cmpl] New user willing to participate in Cmpl develpment

[Mike Steglich]

An additional question ... Is there a way to obtain your solver and also the source code? Knowing that BaPCod is a prototype it would be interesting to take a look on it.

Cheers,

Mike

Then, (and here is the more difficult task) I would like to add in Cmpl the possibility for the user to specify which of the constraints and variables define the subsystems on which the decomposition is based.
