/**

|
* # Response context
|
|
*
|
|
* Figures out which context we are currently serving. The biggest challenge with determining this
|
|
* is that the only way to determine whether or not we are a post, or a page, is with data after all the
|
|
* data for the template has been retrieved.
|
|
*
|
|
* Contexts are determined based on 3 pieces of information
|
|
* 1. res.locals.relativeUrl - which never includes the subdirectory
|
|
* 2. req.params.page - always has the page parameter, regardless of if the URL contains a keyword (RSS pages don't)
|
|
* 3. data - used for telling the difference between posts and pages
