  /*******************************************************************
   *  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();
