Provide title info- description, image along with the adaptation
Since the comparison of HTML after adaptation is very inefficient
and difficult to comprehend, I changed it to just string length
comparison. In a follow up commit, we will try to write unit test
against the TranslationUnit classes by passing the node Object
directly.
