/*! \class UntangleBetaQualityMetric
\brief The untangle beta quality metric.
Given a scalar value beta and local signed element volume alpha_i,
define delta_i to be alpha_i minus beta. The Untangle beta value
is then defined as square root of the sum over sample points
of the absolute value of delta_i minus delta_i, difference squared.
That is, the root mean square of the difference, abs(delta_i) minus
delta_i.
The constructor defaults to RMS AveragingMethod and
ELEMENT_VERTICES evaluationMode. The default beta value is
.05.
