3/// Tests importing/exporting optical surfaces from GDML
4///
5/// Optical surfaces, skin surfaces and border surfaces are imported in object arrays
6/// stored by TGeoManager class. Optical surfaces do not store property arrays but point
7/// to GDML matrices describing such properties. One can get the data for such property
8/// like:
9/// TGeoOpticalSurface *surf = geom->GetOpticalSurface("surf1");
10/// const char *property = surf=>GetPropertyRef("REFLECTIVITY");
11/// TGeoGDMLMatrix *m = geom->GetGDMLMatrix(property);
12/// Skin surfaces and border surfaces can be retrieved from the TGeoManager object by using:
13/// TObjArray *skin_array = geom->GetListOfSkinSurfaces();
14/// TObjArra8 *border_array = geom->GetListOfBorderSurfaces();
15/// Alternatively accessors by name can also be used: GetSkinSurface(name)/GetBorderSurface(name)
