Can't be done, given two points and a radius there are two circles that can
be defined (Unless the distance between the two points is greater than 2R,
in which case there are no circles that can be defined.  In the case where
the distance between the two points is exactly twice the radius, there is
one circle and it's center is midway between the two points.
