Non-bookmarkable pages have no or default constructors and constructors with the PageParameters
argument hidden (protected/private) default contructors and constructors with a PageParameters
argument, or none at all. It could have any other constructor, like MyPage(FooClass bar)
etc. The net effect of your page being non-bookmarkable is that there is no way a user can directly access your page. So, by making a page non-bookmarkable, you make it a 'safe' page.
