Unittestsadded unit tests

Added unit tests for;

- ViewLocator
- RegExHelper
- ViewModelLocator

Extracted StringSplitter from Parser and added unit tests for StringSplitter. 

All this work was made as a part of tretton37's (http://tretton37.com/) open source day where we all gathered and worked with several different open source projects (#1337oss on twitter).

We hope that you'll like it. :-)
