Now that I think about it, annotations could provide a wholly new and
improved way of doing properties. They would be attached to the fields
directly instead of their getter. It could look like this:

@MasonProperty(order=1,
   displayName="Number of Youth",
   tooltip="Number of youth in the model. This reflects the blah blah
blah",
   min=1,
   max=500,
   uiType=Slider,
   disabledWhileRunning=true)
public int numYouth = 140;

There's a lot of power there. Food for thought.
