                        FirstRunWizard.java
  Log:
  The API has been changed. Three new boolean methods have been added. hasPossibleChanges() returns whether a page performs changes to a workspace
  shouldShow() designates whether the page should show anyway, so long as one page hasPossibleChanges()
  isDefaultPage() designates that this page should show even if 0 pages return true for hasPossibleChanges()
