Detailed Description

Computes the condition numbers of the corner's of elements connected to the given vertex and then averages those values.

The metric does not use the sample point functionality or the compute_weighted_jacobian. It uses the isotropic ideal element. This metric does require a feasible region, and the metric needs to be minimized.
