[Tutor] How to add extra Vbox fields dynamically

[Lang Hurst]

OK, I just did the ugliest hack, from someone who only seems to do ugly 
hacks.  I set up a bunch of textview areas and defaulted them to 'not 
visible'.  Then as I loop through my query results, I make them visible 
one at a time.  Well, it works perfect, but it just doesn't seem right 
for some reason.
