This is currently just to maintain consistency with the render phase's RenderContext but in the future it should allow us to include immutable data that is not locked behind the ArcMutex.
This module is mostly the intermediate representation of the AST, so the renaming is to make that more clear. The three forms are parsed => intermediate => render.
Parsed comes from Organic and is a direct translation of the org-mode text.
Intermediate converts the parsed data into owned values and does any calculations that are needed on the data (for example: assigning numbers to footnotes.)
Render takes intermediate and translates it into the format expected by the dust templates. The processing in this step should be minimal since all the logic should be in the intermediate step.
