[x3d-public] Proto expander. Scripts in protobodies without a DEF

Thu Jul 14 17:41:45 PDT 2016

Here’s the MaterialModulatorPrototypeExpanded.x3d from my code.  Please try in all browsers.  I think there’s  a problem with the BooleanToggle—there’s no toggle in X3DOM or Cobweb.  I wll test in some browsers.
