Surf root objects

There are a number of root API objects available. Depending on the context of the object being processed (such as a page, template, or component), the objects available will differ slightly. For instance, when a page is the current context, the "config" object will not be available as there is no configuration at the page level. The context for rendering will be one of: the current page, the template for the page, or a component bound within the template.
