Map grabs the doc sections, giving us an array of arrays. Join, flattens all
the items to a comma delimited string. Split turns it into an array again.

{% assign docs = site.data.docs | map: 'docs' | join: ',' | split: ',' %}

Because this is built for every page, lets find where we are in the ordered
document list by comparing url strings. Then if there's something previous or
next, lets build a link to it.
