[FieldTrip] 2D surface spline interpolation

Dear Ahmed,

there are several functions making use of (spline) interpolation, e.g. 
ft_channelrepair for reconstructing time-courses of missing or bad 
channels, or ft_scalpcurrentdensity for spatial filtering of data. Also 
ft_megrealign is doing some interpolation magic, but I don't know what 
method that function is using. In case you are interested in low-level 
functions, they are in FieldTrip/private, called splint.m and 
sphericalSplineInterpolate.m (afaik both doing essentially the same, 
just different implementations of the same method).
