New Revision: 2957
Log:
Added driver for performing trigger cuts on a readout file, such as data output from a run. This driver assumes that each event contains a wide range (at least 100 ns or so) of clusters and thusly does not need to retain clusters across events for proper management of the time coincidence cut.
