method to collect the variables of a constraint

If the number of variables is greater than the available slots in the variable array, nothing happens except that the success point is set to FALSE. With the method SCIPconsGetNVars() it is possible to get the number of variables a constraint has in its scope.

Note
The success pointer indicates if all variables were copied into the vars arrray.
It might be that a constraint handler does not support this functionality, in that case the success pointer is set to FALSE.
Parameters
consconstraint to print
setglobal SCIP settings
varsarray to store the involved variable of the constraint
