-/**
- * class Markdown
- *
- * Markdown processing in Javascript done right. We have very particular views
- * on what constitutes 'right' which include:
- *
- * - produces well-formed HTML (this means that em and strong nesting is
- * important)
- *
- * - has an intermediate representation to allow processing of parsed data (We
- * in fact have two, both as [JsonML]: a markdown tree and an HTML tree).
- *
- * - is easily extensible to add new dialects without having to rewrite the
- * entire parsing mechanics
- *
- * - has a good test suite
- *
- * This implementation fulfills all of these (except that the test suite could
- * do with expanding to automatically run all the fixtures from other Markdown
- * implementations.)
- *
- * ##### Intermediate Representation
- *
- * *TODO* Talk about this :) Its JsonML, but document the node names we use.
- *
- * [JsonML]: http://jsonml.org/ "JSON Markup Language"
