Insert interior (i.e. volume) points into this element to make the geometry an order order representation.

Parameters
orderThe desired polynomial order.
geomThe geometry object used to describe the curvature mapping.
edgeTypeThe points distribution to use on the volume.
coordDimThe coordinate (i.e. space) dimension.
idCounter which should be incremented to supply consistent vertex IDs.
justConfigIf true, then the configuration Element::m_conf will be updated but no nodes will be generated. This is used when considering boundary elements, which just require copying of face or edge interior nodes.
