Added default behavior, formatting logic, date logic and html templating to hsDate directive.
Deleted this.date; deprecated by hsDate directive.
Allowed for HTML support in hs-date.
Squashed the hsDate update bug. Removed %date% templating, which was the cause. Templating now done in format attribute, html not allowed.
Deleted hs-date.html. It was a file for learning directives and is no longer needed.
