18// Cut on the Event at generator level: for the moment just
19// the requirements on the MB process type, on the number of charged tracks
20// and on the vertex 3-D position are implemented
21// The argument of IsSelected member function (passed object) is cast into
22// an AliMCEvent. In the future may be modified to use AliVEvent interface
23// and to include more cut variables.
24// The class derives from AliCFCutBase
