Widgets

The purpose of this code is to create a convention between a hand crafted html page and the widget netlogo code.  Unfortunately, unless we have the user boot up the engine and associated widgets manually, we have to come up with a sensible identifier.  While having a model with two buttons with identical displays would cause iffy behavior (maybe a check and warning rather than soldiering on?), I considered that to be reasonable in order to provide the html author the most convenient interface.  Unless there's another solution?
