IdealGraphVisualizer: Enhance text view so it can display arbitrary properties from the active graph's group. For diff graphs, it shows the textual difference between the property strings using the NetBeans Diff module.

// I can cast any old thing I want to this type object:
public class You_Have_Been_P0wned {
  // Make a bunch of int-fields so I can peek & poke it
  int _a;
  int _b;
  int _c;
  int _d;

}
