SPR

The Superconvergent Patch Recovery (SPR) library implements a general algorithm for parallel super-convergent patch-based recovery of first and second order nodal fields from integration point field quantities.

It also implements an error estimator based on the difference between a solution field on integration points and its corresponding recovered field.

Helper functions are provided for some operations that are used by SPR but are widely applicable.
