Added better comments at start of pylint-leo.py.
Removed previously commented out code relating to importers & writers.
Removed no-longer used special tests for @org, @otl, etc, but retained test for @auto-rst as part of the fallback policy that uses code in leoRst.py if no plugins exist for rST files.
Add a fallback "except Exception" in to create *all* exceptions in ic.createOutline.
All tests pass.
