Prime function needs to take points in circles

[ehkropf]

The SK prime function should take points inside circles in the unit disk, specifically the image under the "theta-j" maps of a point in the unit domain.

Until the prime code will take such a point (and then use Hejal's identity to get the computation right), the m-file output code cannot build, from the prime function, the "G_j" functions needed to properly express circulation.
