Detailed Description

Auxiliary program to write KM3NETDAQ::JDAQTimeslice with random data.

To pipe data to application JTriggerProcessor.cc whilst maintaining header and meta data, two output files can be specified.
The file names should have extensions ".root" and ".dat", respectively.
The first corresponds to a ROOT formatted file with header and meta data and the second to the pipe with timeslice data.
