[Scip] Extend SCIP with a new constraint handler

[Gerald Gamrath]

Dear Miro,

welcome to the SCIP mailing list!

Did you also include your constraint handler into SCIP? Your constraint 
handler should implement a method SCIPincludeConshdlrXyz(), which you 
need to use to include the constraint handler. For default SCIP, this is 
done in the file scipdefplugins.c in src/scip/, if you started your own 
project based on SCIP (like the examples), you probably want to include 
the constraint handler in the main file of your project.

You can check that your constraint handler was included in SCIP's 
interactive shell by typing "disp cons".

Do you want to read your instance as a .cip file? In this case, the 
constraint handler name stated in front of the constraint (e.g., 
[linear]) must be exactly the same as the name of your constraint 
handler and your constraint handler needs to implements its CONSPARSE 
callback.

Best,
Gerald
