Declaration of alias for the type of data structures which are used to store symmetric tensors. For example, for rank2 symmetric tensors, we use a flat vector to store all the elements. On the other hand, symmetric rank4 tensors are mappings from symmetric rank2 tensors into symmetric rank2 tensors, so they can be represented as matrices, etc.
This information is probably of little interest to all except the accessor classes that need it. In particular, you shouldn't make any assumptions about the storage format in your application programs.
