+// Defines a simple integer rectangle class.  The containment semantics
+// are array-like; that is, the coordinate (x, y) is considered to be
+// contained by the rectangle, but the coordinate (x + width, y) is not.
+// The class will happily let you create malformed rectangles (that is,
+// rectangles with negative width and/or height), but there will be assertions
+// in the operations (such as Contains()) to complain in this case.
