Is there any reason the sim.util.Interval class doesn't have a method to test whether or not a value falls within the interval?

I went ahead and added this method to my local copy:

   public boolean contains(Number val)
        {
        if (val.doubleValue() >= min.doubleValue() && val.doubleValue() <= max.doubleValue())
            return true;
        return false;
        }

It makes using dom sliders and bounds testing a little nicer.  For example:

    public static double lambda = 1.0;
    public double getLambda() { return lambda; }
    public void setLambda(double val) { if (((Interval)domLambda()).contains(val)) lambda = val; }
    public Object domLambda() { return new Interval(0.0, 1.0); }

Full Interval.java file also attached.

Thanks,
