4-points spline option for the semi-Lagrangian interpolation (February 2005)

This is documentation was written by Filip Vana in February 2005 about the new option for the semi-Lagrangian interpolation:
4-points spline. It is supposed to be more precise and accurate than the current
default interpolation requiring almost the same CPU consumption. The only problem
seems to be that for the time being there is probably some minor bug preventing
the scheme to give better results than the default one. Hopefully during summer 2006,
it is going to be rechecked and debugged.
