/**

 *
 * Main program to trigger events in acoustic data.
 *
 * An acoustic event is based on a coincidence of estimated times of emission from the same emitter.\n
 * If the number of coincident times of emission exceeds a preset minimum, 
 * the event is triggered and subsequently stored in the output file.\n
 * Note that an event counter is added which can be used to disambiguate 
 * the different cycles from the same emitter within one "super" event that is used for the global fit.\n
 * In this, a super event refers to the coincidence of events from a variety of emitters.
