Specs/wikitext/1.0.0

MediaWiki's Wikitext flavor is primarily defined by its implementations in MediaWiki itself and Parsoid. These entry points should be helpful:
 * The Wikitext Help page on Wikipedia.org provides a high-level overview.
 * parserTests.txt defines over 800 input / output pairs, which are executed in CI tests for both the PHP parser and Parsoid.
