title: Get page title of a native app using appium
body: <p>It doesn't seem that appium now has a direct way to get and verify the page title of a native app, similar to the way it works on a web using the <code>driver.getTitle();</code> method. Is this correct?</p>
  
  <p>An indirect way I am using is the <code>driver.findElement(By.xpath("")).getText();</code> method on the page header text and then assert that the text is correct. With this method, there is no proof that the text fetched is definitely the title of the page as the text could also be contained in any part of the page. </p>
  
  <p>Has anyone got a more genuine way of getting and verifying the page title of an iOS native app?</p>
