A PageReference is used by PageModules to point to the parent PageObject or PageModule.
It provides webDriver access, this is implemented for PageModules by delegating to
the parent and for PageObjects by delegating to the PageBrowser.
All calls to Locator have an implicit PageReference, allowing the Locator to ask
for the Element to search in. When root returns None the full page will be searched.
