[kepler-dev] [Bug 4197] - Waterflow TPC demo - tracking bug

[ben leinfelder]

Edward -
I suppose I drew some conclusions from this line (in DoubleToken.java):

     public static final DoubleToken NIL = new DoubleToken(Double.NaN);

I've changed the reporting class to keep "nil" rather than "NaN" when  
it is rendered.
Thanks!
