----------------------------------------------------
  * connectedSpaces, buildingsExtRings, patios = STConnectedSpacesAndPatios(inputLayer, buffDist=0.0).execute()
  * skeleton, nodes, voronoi = STSkeletonizeTheVoid(buildingsExtRings, samplingDist=10.0).execute()
     => la skeletonization ne cree plus que 3 couches, les retourne en sortie, et ne prend plus de smoothingDist puisqu'elle ne simplifie plus automatiquement les donnees d'entree. Il faut explicitement invoquer STConnectedSpacesAndPatios prealablement a la skeletonization
  * indic = STSpatialAttributeCommand([AreaConvexityDefect, GraveliusIndex, MillerIndex ], intersections, outputLayerName=None).execute()
  * STKernel a disparu - elle est remplacee par STSpatialCommand(Kernel, ...)
