Converts a set of tabulated azimuth and altitude values to a bspline curve that ultimately produces a sun direction.
Sun position data can be copied from the tabulated view of the sun path diagram in Ecotect 5.6 , or from several other web sources (if anyone wants to tabulate these that's be great)
the three columns are for the two equinoxes, and the mid point of the year.
