Add support group element.

[mhemesath]

I think we can simulate the "g" element. In append if we treat "g" as a special case, we could return a special D3 group selection which is basically a Raphael set. If a transformation is applied to the group, it will apply it to every element in the set. Likewise, it will store the transformation string and apply it to all elements that are "appended" to it. This should be a pretty close simulation to actual SVG group elements except they can't be "selected" and directly apply all attributes to the elements in the set (unless we limit it to transformations).

Let me know your thoughts on this and I can probably start working on it.

Has anyone attempted any work on this?

I've stopped working on this project as I've gotten very little feedback from a pull request I've made. Since then, I've found a much easier way to extend D3 for IE compatibility so I just made my own project being it is almost entirely different.

Thanks for the quick reply.

Your project seems like a good alternative, thanks, I'll give it a spin and
maybe get involved. :)
