Detailed Description

Let the tensor \(\mathbb{C}\in\mathbb{R}^3\times\mathbb{R}^3\times\mathbb{R}^3\times\mathbb{R}^3\) be fully symmetrix such that \(\mathbb{C}_{ijkl}=\mathbb{C}_{\sigma(i,j,k,l)\) where \(\sigma\) is any permutation. Then there are only 5 (2D) or 15(3D) unique elements (rather than 81).

This object acts like a 4D array such that C(i,j,k,l) returns the corresponding element, but symmetry is always obeyed. This allows the user code to be much prettier.
