"""Test every proposed Man in the Iron Mask candidate against the seven fixed points.

Reads ../data/fixed_points.json and ../data/candidates.json and prints a markdown
table (default) or JSON.  A candidate "passes" a fixed point when no document
contradicts him at that date; "fails" when a document places him elsewhere,
free, or dead; "open" when the documents do not decide; "na" when the point does
not apply.  The statuses and notes are the analyst's readings of the documents
cited in the two JSON files; the script only tabulates them.

Usage:  python3 fixed_points.py [md|json]
