Merge 0-0-stable from private Representors into develop

So @HonoreDB  this required a little git chicanery.  I swapped origins, and it looks like the history came through intact.  This is the 0-0-stable branch from mdsol/representors.  If this is merged, I'd like to recreate an 0-0-stable branch on this repo as well.  Most of that line count is the hale test fixtures, btw.
