##CIRCLES3D Description of functions operating on 3D circles
##
## Circles are represented by a center, a radius and a 3D angle
## representing the normal of the plane containing the circle.
## C = [xc yc zc R theta phi psi].
## THETA is the colatitude of the normal, in degrees, between 0 and 180
## PHI is the azimut of the normal, in degrees, between 0 and 360
## PSI is the proper rotation of the circle around the normal, between 0
## and 360 degrees
## The parameter PSI is used to locate a point on the 3D circle.
