Raise exceptions when element not found

[tomasserravento]

Hey mate, how are you? I hope you are doing well!

I have this small suggestion: it would be amazing when an element is not found that an exception is being raised (such as Selenium does). It is quite annoying to have to check the returned string.

Im going to push soon swith_to additions!

Thanks for the amazing work!
