Parameters

pAlgorithm	the address of the master instance, used to access MCParticles when in training mode
nuSliceHypotheses	the parent pfos representing the neutrino outcome for each slice
crSliceHypotheses	the parent pfos representing the cosmic-ray muon outcome for each slice
sliceNuPfos	to receive the list of selected pfos
