Had some problems with maven, so I added the expected java version
Added a method to ContentExtractor that allows you to extract only the main article text (had to add some other stuff to coupled code)
Adding a testdata directory
Added a test case for the new 'text only' extraction method
Added: maven assembly descriptor
Bug fix: text extraction method should return an empty string when no content is found
