New articles on lists and joins

[mwra (Mark Anderson)]

Some recent experience on being asked to make JSON data from a research project lead to updates/new articles in aTbRef (in no particular order):

• Export: loops and joins.
• ^nextSibling^, ^previousSibling^ and a reason to pull ^not(condition)^ off the redacted shelf and back into the corpus.
• Action code loops:
  • Using .each() for loops.
  • Constructing $Attribute references in loops.
  • Detecting first or last item context in loops.
  • Adding joins in loops.
• List/Set.first() and List/Set.last().

All changes are live, including updates to the sitemap page and the zip of the source TBX.
