public class ERD2WQueryPage
extends ERD2WPage
implements ERDQueryPageInterface

Superclass for all query pages.
In addition to the rest of the goodies of ERD2WPage, it lets you save and restore the initial query bindings by supplying a NS(Mutable)Dictionary which contains the keys "queryMin", "queryMax" etc from the respective fields of the WODisplayGroup.
