LayerCreator: Modules not associated to Layer (was ACTS-246)
Original author Valentin Volkl @vavolkl
All surfaces representing modules in my DD4hep-Plugin-built tracking geometry return a nullptr for associatedLayer(). This also seems the reason the extrapolation example only found layer surfaces for my geometry-- at least I started seeing PlaneSurfaces after I tried to add calls to associateLayer() in the Plugin.
