/**
 * \defgroup NumericalDiff_Module Numerical differentiation module
 * \brief Finite-difference Jacobians and differentiation weights.
 *
 * \code
 * #include <contrib/Eigen/NumericalDiff>
 * \endcode
 *
 * See http://en.wikipedia.org/wiki/Numerical_differentiation
 *
 * Warning : this should NOT be confused with automatic differentiation, which
 * is a different method and has its own module in Eigen : \ref
 * AutoDiff_Module.
 *
 * This module provides the following classes:
 * - \ref NumericalDiff extends a functor with Jacobian computation using
 *   \c Forward or \c Central finite differences at a fixed step.
 * - \ref Ridders stores a functor and computes its Jacobian using adaptive
 *   central differences and Richardson extrapolation, with optional error estimates.
 * - \ref Stencil computes finite-difference weights for arbitrary fixed-size
 *   grids and derivative orders, using points and a step size chosen by the caller.
 *
 * Also, the \ref NonLinearOptimization_Module needs this in order to
 * provide full features compatibility with the original (c)minpack
 * package.
 *
