Hey,

I'm using the HTML5 step attribute and your wizard "step" directive is conflicting with it. Can we prefix your step directive with mgo- or something to fix this namespacing issue?

You can see the step attribute explained on MDN at https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Input.

This conflict resulted in the following error: Controller 'wizard', required by directive 'ngTransclude', can't be found.

I can open a PR for this if you'd like to proceed with this proposed fix.
