/*
 * AF2LocalTransform.hpp
 *
 * A local transformation between some 2-dimensional space and some
 * 2-dimensional subspace of a 3-dimensional space.  This transformation
 * is used by the 2-dimensional advancing front algorithm to transform
 * points between a surface embedded in 3 dimensions and a 2-dimensional
 * space.  The transformation should be a bijection between the
 * 2-dimensional space and some local patch on the surface, but
 * it does not need to be a global parametrization.
