DESCRIPTION

start_component_hook CONTEXT_OBJECT

Whenever we start to render a component, check to see if we can draw a halo around the component.

Either way, record halo metadata.

end_component_hook CONTEXT_OBJECT

When we're done rendering a component, record how long it took and close off the halo "span" if we have one.

_unrendered_component CONTEXT

Returns true if we're not currently inside the ``Body'' section of the webpage OR the current component is a subcomponent. (Rendering halos for subcomponents being too ``heavy'')

render_component_tree

Once we're just about to finish rendering our HTML page (just before the "</body"> tag, we should call render_component_tree to output all the halo data and metadata.
