Detailed Description

This parses the gGeoManager and looks for a defined combination of volume with contained sensitive detector element.

The association is done by matching the names of the TGeoNode / TGeoVolume to the search string.

The parsing can be restricted to a given parse volume (in r and z), and given some splitting parameters the surfaces can be automatically split into layers.
