Example steering file to test the reconstruction.
First run validation/generateRawData/generateRawData2 with the
gear_tpc_proto_circular.xml file to generate input sclio data.

Afterwards call Marlin with the reconstruction_curler.xml file.
Remember that the MARLIN_DLL variable has to contain libMarlinTPC.so !

Finally you can call Marlin with dumpPadCentres.xml or dumpHitsInTracks.xml to
dump the coordinates of all pads which were hit or of all reconstructed hits
in tracks to the console.

generateRawData2 works with gear_tpc_proto_circular.xml,
which is a circular geometry.
The data is a curler which makes more than 3 loops within the TPC.
