This is preparation for removing the `servo-` prefixes from the various Servo components.
…data directly. Nodes are now parameterized over a "View" type. The particular View type determines which methods can be called. Layout data accessors and mutators are only accessible to nodes with a LayoutView. The only way to convert a `Node<ScriptView>` to a `Node<LayoutView>` is through a transmutation, which is done at the moment the layout task receives nodes. (This should be factored better to contain the unsafety.) We should also lock down DOM node mutation to the ScriptView to forbid data races, but this patch doesn't do that. This also reduces coupling between DOM and layout. Soon I would like to move the DOM into its own crate, and this is a step on the way of doing that.
…ut interface. Eventually, the layout interface will be moved along with the DOM into a separate crate.
Premature abstraction; nothing used the traits polymorphically. Furthermore, they increased coupling between layout and the DOM.

Add crate docstring and two code examples In the hopes of embedding SpiderMonkey into a non-Servo Rust project, I spent some time digging into these bindings. Unfortunately, it was very easy to get lost. This PR is my attempt to make it easier for the next person who attempts my exercise by adding a few sign posts I would have found helpful, and translating one of the basic examples from the SpiderMonkey User Guide on MDN to Rust. Documenting the entire crate (and where it dips directly into ``mozjs_sys``) is a task too big for any one person, I think. EDIT: removed WIP comment

This rolls up some of the changes you've done.
I'm not quite happy with the way all render boxes have box model parameters, even if they aren't box model objects. I see now why WebKit has
RenderBoxModelObject. Perhaps we should do the same and only make room for border/padding/margins for generic boxes and image boxes.
