/**\class PythiaProbeFilter PythiaProbeFilter.cc
Description: Filter to exclude selected particles from passing pT,eta cuts etc. Usefull when we are interested in a decay that its daughters should not pass any cuts, but another particle of the same flavour should e.g B+B- production with B+->K+mumu forcing (probe side) and we want mu to come from B- (tag side)
