Detailed Description

An intermediate helper struct that defines the return type of Hessian (second derivative) calculations of scalar fields with respect to fields defined by the two extractor-type template parameters. This particular specialization is for taking the first derivative with respect to a scalar field, and the second with respect to a symmetric tensor field.
