Detailed Description

Creates and runs a simple iterator plugin connected to TGeoPainter iterator.

It demonstrates the possibility to dynamically change the color of drawn volumes according some arbitrary criteria WITHOUT changing the color of the same volume drawn on branches that do not match the criteria.

To run:
root[0] .L iterplugin.cxx+
root[1] .x runplugin.C
root[2] select(2,kMagenta);
root[3] select(3,kBlue)

void runplugin()
TString tutdir = gROOT->GetTutorialDir();
gROOT->ProcessLine(".x " + tutdir + "/geom/rootgeom.C");
plugin = new iterplugin();
void select(Int_t replica=1, Int_t color=kGreen)
// Change current color. Replica range: 1-4
plugin->Select(replica, color);
