Refractor and add directive.

[ItayZiv]

I have already started working on something related, but I'm opening an issue for discussion.
My idea right now is to split everything into separate files as fit, so files for the following:

• file to handle getting the description/cleaning up the title
• file to handle inserting the tags
• file to handle the directive
  Is what currently comes to mind.
  As for the directive, it would have an override for the image, the description, and the type, plus additional metadata that fit certain types (For example, the article type, and its metadata (publish time, author, etc etc)

If anyone has any comments/ideas feel free to comment
