Looking at this a little more deeply, I see that this works, in the case 
of the OnConsoleStatusListener, via simply writing on the console.  But 
it seems that the level you choose to add (addInfo() vs addWarn() for 
example) affects only the status reported on the output device and there 
is no filtering available based on these "levels".  Is this correct?
