The Jinja2 service was treating all the task data as a possible template, modified it to only include the referenced templates.
(This turned out not to be the problem, but it seems like a good idea to keep it in place)
There is a terrible bug with the wordwrap pipe that will die without any details if you pass it a value of None. We now cature the terrible error, and replace it with a sensible one.
Removed an unused Jinja_extensions file.
Migrating the complete_template script stuff to JinjaService.
Having trouble with the tools stuff.
Pulled back to spot where test pass using CompleteTemplate
