/*
 The custom designed view. This class actually has the lion's share of the code just because the view and its behavior is pretty complex.
 Note, while the view is a heavy class, this is still MVC- it's just a very complex V.
 
 The PolyView is responsible for displaying the regular polygon currently selected by the slider. It supports animation and swipes.
