place a `yml` file in the posts directory of a blog, and the default listing behavior will merge the contents of the yaml file into the listing. 

- Also will emit NaN min if reading time is enabled. Should not emit this.
- Should not include yaml files in listing in this way (unless user asks for yaml files)
