Fixes #27 Ambiguous use of 'description'

[briancprice]

You may want to just add the description property to the tag class, but this was the least modification I could make. Thanks

First off... congratulations on your first PR! Looks great :)

This makes sense, we just need tag to conform to CustomStringConvertible through Renderable and this does just that.

But, since we are only working with tag now, maybe this makes more sense in the tag class itself as opposed to sitting as an extension. Can you delete this extension and just move the public var description: String { that returns render() into the tag class?

I can merge this in after :)

Thanks! And thank you for writing this pod, saved me a ton of time generating HTML to convert to PDF for my app!

Perfect! Merging...
