// To get an numerically differentiated cost function, you must define
// a class with a operator() (a functor) that computes the residuals.
//
// The function must write the computed value in the last argument (the only
// non-const one) and return true to indicate success.

// Please see cost_function.h for details on how the return value
// maybe used to impose simple constraints on the parameter block.

// For example, consider a scalar error e = k - x'y, where both x and y are
// two-dimensional column vector parameters, the prime sign indicates
