Special Version of Gradient Using CppAD
#######################################

valvector
*********
This version of the CppAD gradient handles the case where the base type
for differentiation is ``valvector`` instead of ``double``.
This is a CppAD example type that evaluates numerical operations on vectors
(similar to ``std::valarray`` numerical operators).
One important difference is that a scalar (one element vector) does
not allocate any memory and can operate with any sized vector.
