[Cbc] wrapper to create matrix via variables/constraints (not rows/columns)

[Stefan Vigerske]

Hi,

there are FlopC++ (https://projects.coin-or.org/FlopC++) and Rehearse 
(https://projects.coin-or.org/Rehearse) that should let you do something 
like that.
FlopC++ is no longer developed, but might still be working.
