/// RefInt - a reference to an int
// <P>
// Used to pass ints to methods by reference, so they can be modified.
// You can't use the standard Integer/Long/Float/Double classes for this,
// because they are immutable - the number they represent can't be changed
// once the object is created.  With these Ref classes, on the other hand,
// you can change the value all you want
