Analysis of L2 headers
Notes:
 * All L2 headers should be languages or "Translingual"
 * This program uses the 2- and 3-letter language code templates; a number of languages are listed as invalid because they lack code templates, or the form of the template doesn't match the form used as an L2 header
 * The "wiki code" is a code derived from an ISO language group and another code used within the Wikimedia projects for languages that do not have an ISO 639-3 code.
 * This is an analysis, it is not a policy document
