Distance of a circle to a line in 3d

Calculate the nearest points on a circle with respect to a line in 3d
A line is defined by a point and a vector in 3d.
A circle is defined by a midpoint and a radius and the normal vector of the supporting plane, the circle lies inside.
This function calculates the nearest point (and the minimal distance) of a circle to a line in 3d.
Function is not vectorized, as too many special cases can occur.
I have not developed the algorithm itself. The algorithm has been originally implemented by David Eberly, Geometric Tools, Redmond WA 98052 !
Kudos also to Aaron T. Becker's Robot Swarm Lab's comments on an erroneous case.
