/*! \class LPtoPTemplate
\brief Calculates the L_p objective function raised to the pth
power. That is, sums the p_th powers of (the absolute value of)
the quality metric values.
\todo MB. Suggestions made by Todd Munson:
a) There is an inconsistent use of fabs. The hessian evaluation
when using the one norm does not take the absolute value, while the
gradient does.
b) The analytic gradient and hessian evaluations are incorrect when
the quality metric changes sign due to taking the absolute value.
The negative of the element gradient and hessian also needs to be
taken.
c) Done. The analytic gradient and hessian evaluations are
incorrect when the negate flag is set to -1. The negative
of the element gradient and hessian also needs to be taken
in this case.
d) The malloc in the concrete_eval routine should be removed.
