I need to calculate the bounding box of a set of points.
That is, the smallest rectangle which will encompass
all the points.  I decided that I could simply find the greatest
x value among all the points, the greatest y value, and then
the least x and y values to find the edges of my box.  To
easy, I decided.

How can I calculate a bounding circle?  Anyone know?

Also, If I use bounding circles, I need to be able to check
if the bounding circle is intersected or contained by two rays
which extend from a single point at a slight angle from one another
(I'd do some ASCII art here, but my mailer uses a proportional font).
How can I do this? (quickly!)

Much thanks and appreciation to whoever helps me out.
