title: SCIP using old code
body: <p>I am kind of new to the SCIP. I want to use SCIP as a branch and price framework. I have coded the problem in C++ already and also have implemented the pricer or column generation as a function. In fact I have implemented the BP algorithm for the root node by linking Cplex.dll to the project and now need to code the branching tree and decided to use SCIP for this purpose.
  I want to know what is the fastest way I can solve my problem using SCIP and the old codes which I have? Or  maybe using GCG is a better and faster way? 
  I have read the GCG documentation but doesn't understand if I should implement the pricer myself again or not? In fact I don't understand the difference between these two (SCIP and GCG).
  Thanks.</p>
