The problem:
	Find a nice formula for the distance between
	arbitrary circles in 3 dimensions.

The circles can be in any orientation relative to one
another.  The distance is defined to be the minimum
distance between any two points on the circles.
The circles could intersect, for instance.

I hesitate to submit this because I wanted to do it
myself.  I don't know if there IS is a nice formula!
Maybe I'll figure it out before anyone sends the answer...
