The main changes affect GeoModelKernel and GeoModelIO: * For the GeoVGeometryPlugins, the interface was changed. Now written to the GeoVPhysVol interface, allowing either full or ordinary phy vols to be created from a plugin. * Bug fix in GeoModelWrite (all phys vols stored and phys vols) and greater generality in GeoModelRead (either fullphysvols or physvols are resolved at the top of the geometry tree) * Update GeoModelExamples, GeoModelTools, and GeoModelVisualization to new interfaces
