[Cbc] cbc.branchAndBound vs CbcMain

[Haroldo Gambini Santos]

Hi Matthew,

If you use CbcModel you will have to include cuts, pre-processing and 
heuristics in your code too (CbcModel just comes with branch and bound 
and strong branching). You'll have also to tune also every object added 
to CbcModel. It is not straightforward to reproduce the good results of 
CbcMain with CbcModel.
