- *  Markdown processing in Javascript done right. We have very particular views

- *
- *  - 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
