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