Patch to prepare NonLinearOptimization for complex numbers

Basically the Levenberg-Marquardt algorithm should work for complex numbers, too. However, there are a number of quantities which remain real, no matter whether the underlying space is complex or real-valued.

Basically I introduced a typedef NumTraits<Scalar>::Real RealScalar and reset all real quantities to that type.

However, since I am not an experienced Eigen developer, I would like someone to review the patch before committing it.

Apart from this I added some documentation to the LevenbergMarquardt class, which now at least describes the expected format of the functor to pass.
