> added WebElement.click_safe() method, in case you get detected
after clicking a link > added WebElement.children(self, tag=None, recursive=False) to easily get/find child nodes > added example.py where i can point people at when asking silly questions (no, its actually quite cool, everyone should see it) > some refactoring
