Switched completly to By-Expression 

I think this brings a better performance, cleaner code and more flexibility.

Fix #64 
Sorry for the inconvenience diff. The file `./JTAF-ExtWebDriver/src/main/java/org/finra/jtaf/ewd/widget/element/Element.java` was a DOS-file(CRLF) in the repository. Now it is the normal git standard UNIX-Style (LF). I would recommend to follow the standard git-format and enable `core.autocrlf=true` in your settings. Otherwise it should be documented how to handle it. Perhaps you can diff this pull request with an external tool and ignore whitespace-changes.
