Add the GradientChecker.

The GradientChecker is a utility class written by
William Rucklidge that can be used to check that the
derivatives returned by a cost function match those
returned by numerically differentiating the residuals
returned by the same cost function.

This is useful when developing CostFunction objects
and testing them before plugging them into an optimization
problem.
