creates a separator and includes it in SCIP with its most fundamental callbacks. All non-fundamental (or optional) callbacks as, e.g., init and exit callbacks, will be set to NULL. Optional callbacks can be set via specific setter functions, see SCIPsetSepaInit(), SCIPsetSepaFree(), SCIPsetSepaInitsol(), SCIPsetSepaExitsol(), SCIPsetSepaCopy(), SCIPsetExit().

Note
if you want to set all callbacks with a single method call, consider using SCIPincludeSepa() instead
