Spider class.

A spider view is a handy way to visualize a set of data stored in a TTree. It draws as many polar axes as selected data members. For each of them, it draws on the axis the position of the present event between the min and max of the data member. Two modes are available:

The spider view: With each points on the axes is drawn a polyline.
The segment view: For each data member is drawn an arc segment with the radius corresponding to the event.

The spider plot is available from the treeviewer called by "atree->StartViewer()", or simply by calling its constructor and defining the variables to display.

   TCanvas *c1 = new TCanvas("c1","TSpider example",200,10,700,700);
   TFile *f = new TFile("$(ROOTSYS)/tutorials/hsimple.root");
   if (!f || f->IsZombie()) {
      printf("Please run <ROOT location>/tutorials/hsimple.C before.");
      return;
   }
   TNtuple* ntuple = (TNtuple*)f->Get("ntuple");
   TString varexp = "px:py:pz:random:sin(px):log(px/py):log(pz)";
   TString selectStr = "px>0 && py>0 && pz>0";
   TString options = "average";
   TSpider *spider = new TSpider(ntuple,varexp.Data(),selectStr.Data(),options.Data());
