/*! \class IdealWeightMeanRatio
\brief Computes the mean ratio quality metric
of given element.
The metric does not use the sample point functionality or the
compute_weighted_jacobian. It evaluates the metric at
the element vertices, and uses the isotropic ideal element.
It does require a feasible region, and the metric needs
to be maximized.
