/// REVISION HISTORY:\n
///    27 June 2011 : Richie Bonventre - first version
///    13 Nov 2014 : Eric Marzec - Made myself contact person.
///
///  \details  This processor attempts to tag only pickup events.
/// Since pickup waveforms should be bipolar, it should integrate
/// out to zero, so we look for low charge events.
