When comparing our implementation of the Perrin method (fitting surface splines) in ft_scalpcurrentdensity with Brainvision Analyzer's implementation I noticed we're not applying a regularization parameter, which is very useful in case of noisy data.

I've updated ft_scalpcurrentdensity and ./private/splint to implement the regularization and I made it possible to specify the order and degree of the legendre polynomials without hacking the code. Sending ft_scalpcurrentdensity.m Sending private/splint.m Transmitting file data .. Committed revision 10310.
