  wxWizardPageSimple is the simplest possible wxWizardPage implementation: it just returns the pointers given to its constructor from wxWizardPage::GetNext() and wxWizardPage::GetPrev() functions.
  This makes it very easy to use the objects of this class in the wizards where the pages order is known statically - on the other hand, if this is not the case you must derive your own class from wxWizardPage instead.
  Default constructor.
  A helper chaining this page with the next one.
  Notice that this method returns a reference to the next page, so the calls to it can, in turn, be chained:
  This makes this method the simplest way to define the order of changes in fully static wizards, i.e. in those where the order doesn't depend on the choices made by the user in the wizard pages during run-time.
  A convenience function to make the pages follow each other.
  Example:
  Creates the wizard page.
  Must be called if the default constructor had been used to create the object.
  Sets the next page.
  Sets the previous page.
