There's no need to put the error variables in a larger scope, nor define
them earlier than necessary. If anything, it makes the code harder to
follow, such as figuring out when nil errors are returned.
- Refactored API calls to be cleaner
- Changed types that shoudn't be exported to not-exported
- Updated examples with API changes
- Added unit test for Title action
Changed implementation of ElementVisible/ElementNotVisible to use a
javascript evaluation instead of the previous, cumbersome
implementation. As this may not work correctly in all scenarios, the old
versions will remain as ElementVisibleOld and ElementNotVisibleOld until
the new implementations can be vetted for correctness/performance.
