-Markdownify
-===========
-* handle non-markdownifiable lists (i.e. `<ul><li id="foobar">asdf</li></ul>`)
-* organize methods better (i.e. flushlinebreaks & setlinebreaks close to each other)
-* take a look at function names etc.
-* is the new (in rev. 93) lastclosedtag property needed?
-* word wrapping (some work is done but it's still very buggy)
-
-
-Markdownify Extra
-=================
-
-* handle table alignment with KEEP_HTML=false
-* handle tables without headings when KEEP_HTML=false is set
-* handle Markdown inside non-markdownable tags
-
-
-Implementation Thoughts
-=======================
-* non-markdownifiable lists and markdown inside non-markdownable tags as well as the current
- table implementation could be rewritten by using a rollback mechanism.
-
- example:
-
- <ul><li>asdf</li><li id="foobar">asdf</li></ul>
-
- we come to `<ul>`, know that this might fail and create a snapshot of our current parser
- we keep on parsing and when we reach `<li id="foobar">` we gotta rollback and keep this
- list in HTML format.

-/**
- * Markdownify converts HTML Markup to [Markdown][1] (by [John Gruber][2]. It
- * also supports [Markdown Extra][3] by [Michel Fortin][4] via Markdownify_Extra.
- *
- * It all started as `html2text.php` - a port of [Aaron Swartz'][5] [`html2text.py`][6] - but
- * got a long way since. This is far more than a mere port now!
- * Starting with version 2.0.0 this is a complete rewrite and cannot be
- * compared to Aaron Swatz' `html2text.py` anylonger. I'm now using a HTML parser
- * (see `parsehtml.php` which I also wrote) which makes most of the evil
- * RegEx magic go away and additionally it gives a much cleaner class
- * structure. Also notably is the fact that I now try to prevent regressions by
- * utilizing testcases of Michel Fortin's [MDTest][7].
