Detailed Description

Example application to search for sets of consecutive hits on a given PMT,
that are separated in time by a constant value.

The number of consecutive hits
as well as the time difference are selected from the command line.
The searches are done within the JDAQSnapshotHits from JDAQEvents\ as well as within the JDAQHits from the JDAQTimeslice data.
