smoothing with cubic splines by d.s.g. pollock

- b-splines seem to have the highest continuity in general, but go only through the first and last point
- natural cubic splines seem to have the highest continuity while going through all points
- nurbs seem to be a generalisation of b-splines which seem to be a generalisation of bezier curves
- hermite and catmull-rom interpolation seem to be variations of cubic interpolation
- interpolation, curve fitting and splines: interpolation goes at least to start and end points, curve fitting approximates a curve between values, splines combine interpolation piecewiese
- gsl can do only one and two dimensional interpolation
- energy-minimising curve fitting might be a topic of interest
