/*******************************************************************
* This macro displays geometrical information related to the
* hits, digits and rec points (or V2 clusters) in TARGET.
* There are histograms that are not displayed (i.e. energy
* deposition) but that are saved onto a file (see below)
*
* INPUT arguments:
*
* Int_t evesel: the selected event number. It's =0 by default
*
* Options: Any combination of:
* 1) subdetector name: "SPD", "SDD", "SSD", "All" (default)
* 2) Printouts: "Verbose" Almost everything is printed out:
* it is wise to redirect the output onto a file
* e.g.: .x IlcTARGETGeoPlot.C("All+Verbose") > out.log
* 3) Rec Points option: "Rec" ---> Uses Rec. Points (default)
*
* 4) ClustersV2 option: "ClustersV2" ---->Uses ClustersV2
* otherwise ---->uses hits and digits only
* Examples:
* .x IlcTARGETGeoPlot(); (All subdetectors; no-verbose; no-recpoints)
* .x IlcTARGETGeoPlot("SPD+SSD+Verbose+Rec");
*
* filename: It's "gilc.root" by default.
* isfastpoints: integer. It is set to 0 by defaults. This means that
* slow reconstruction is assumed. If fast recpoint are in
* in use, isfastpoints must be set =1.
*
* OUTPUT: It produces a root file with a list of histograms
*
* WARNING: spatial information for SSD/DIGTARGET is obtained by pairing
* digits on p and n side originating from the same track, when
* possible. This (mis)use of DIGTARGET is tolerated for debugging
* purposes only !!!! The pairing in real life should be done
* starting from info really available...
*
* COMPILATION: this macro can be compiled.
* 1) You need to set your include path with
* gSystem->SetIncludePath("-I- -I$ILC_ROOT/include -I$ILC_ROOT/TARGET -g");
* 3) If you are using root instead of ilcroot you need to
* execute the macro loadlibs.C in advance
* 4) To compile this macro from root (or ilcroot):
* --- .L IlcTARGETGeoPlot.C++
* --- IlcTARGETGeoPlot();
