Operations on structural element liners.

Liner elements use the same internal formulation as shell elements. By default, they are deformable, connected to their surroundings in all directions. They are assumed to be placed on a surface of the model, and, therefore, link interactions normal to the element surface are directional. They are unique in the structural element logic for the ability to support two links on each node, allowing liners to be embedded between two surfaces (using the embedded keyword during creation).
