new feature to split a 2nd-order symmetric tensor into a positive part and a negative part

split a 2nd-order symmetric tensor based on the signs of the eigenvalues obtained from a spectrum decomposition, also provide the corresponding 4th-order tensors that are the derivatives of the positive/negative part of the tensor with respect to the original tensor.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
