+ *
+ *	Initial construction creates an inverted box signifying an Empty box instead
+ *	of an infinitely small box at 0,0,0.  Keep this in mind when asking for
+ *	Min or max on a box that has had no points added to it.
+ *
+ *	Transforming a box simply transforms all eight corners to span a new
+ *	axis aligned bounding box.  Successive transformations can thus create a
+ *	non-optimal box, much larger than needed.
