Correcting property, Also moved Skeletondict inside a sub dict, so format of SkeletonDict, 0:{ 'Body':None, 'Include':[] }, keeping tack on Skeleton Thru body... Totally compatible with property. and Include branch will keep include header added later... Change was possible with uses of Property. They inspects the holder anyway and might be changed... Uniformizing them will imply having another Property between VarDefSkeleton, AddSkeleton to update the current property-Index of this derivation.
