[Cbc] CBC warm start

[John Forrest]

Babak,

Rather a broad question as you give no clue how A and B are related.

What do you mean by setWarmstart? Nothing of that name exists.

setHotStartSolution might help - the idea is that it tries to branch 
towards a given solution, but gives up when infeasible - but may be 
close to a solution.
