d4.06.02 sd_ligrel and sd_model Data Structure

Summary:

The sd_model data structure represents the result of assigning finite elements to the cells of a mesh.

An sd_ligrel data structure is a list of groups of finite elements of the same type.

Note: The sd_model is not the only data structure that can contain an sd_ligrel.
