This should just be an accessor method, it's not supposed to *do* anything. The idea is that as soon as you initialise a view object, it's visible (i.e. on line 24 above), so you shouldn't have to also then call `draw-node` on it.

Also, the `Node` does not deal with the drawing of wires, each wire should deal with its own drawing.

This method should just return the paperjs group that represents the node on the screen (and just that, not the wires as well). And this paperjs group should be controlled by the `NodeView` instance (in this case, `@active-wire`.

So, this method should basically look like this:

    view : -> @active-view?group!

and that's *it*. (I'm pretty sure I told at least @tlear and @TygerBurning this at some point.)
