//Piotr Skowronski@cern.ch
//Classes fAnd single particle cuts
//User should use only AliHBTParticleCut, eventually EmptyCut which passes all particles
//There is all interface fAnd setting cuts on all particle properties
//The main method is Pass - which returns 
//        True in Andder to reject particle
//        False in case it meets all the criteria of the given cut
//
//User should create (and also destroy) cuts himself 
//and then pass them to the Analysis And Function by a proper method
