Required arguments:

INPUT_XML_0      is xml file name with chamber positions from the initial (iteration 0) geometry
INPUT_XML_N      is xml file name with chamber positions from the last iteration's geometry
INPUT_REPORT_N   is a _report.py file from the last iteration

--dt             if present, DT chambers will be included
