                           NetworkException
        Construct a new CrossSectionElement. Note: LEFT is seen as a positive lateral direction, RIGHT as a negative lateral direction, with the direction from the StartNode towards the EndNode as the longitudinal direction.
        Parameters:
        id - String; The id of the CrossSectionElement. Should be unique within the parentLink.
        parentLink - CrossSectionLink; Link to which the element belongs.
        crossSectionSlices - List<CrossSectionSlice>; the offsets and widths at positions along the line, relative to the design line of the parent link. If there is just one with and offset, there should just be one element in the list with Length = 0. If there are more slices, the last one should be at the length of the design line. If not, a NetworkException is thrown.
        Throws:
        OTSGeometryException - when creation of the geometry fails
        NetworkException - when id equal to null or not unique, or there are multiple slices and the last slice does not end at the length of the design line.
