Detailed Description

Callback class to gather and process data from many tracks at a single step.

The filtering mechanism allows different step interfaces to gather data from different detector volumes. Filtered step interfaces cannot be combined with unfiltered in a single hit collector. (FIXME: maybe we need a slightly different class hierarchy for the two cases?) If detectors are in use, and all StepInterface instances in use by a StepCollector select the "nonzero_energy_deposition" flag, then the StepStateData::detector entry for a thread with no energy deposition will be cleared even if it is in a sensitive detector. Otherwise entries with zero energy deposition will remain.
