closes #1818 Previously, the markdown of some chapters was converted to Jade markup to support the conditional exclusion of TS prose parts in Dart chapters. This commit reverts some of that back to clean markdown, thanks to a few custom directives.
Why the _fragments dir is checked in
Within this repo files generated as a result of shredding the _examples dir ( the contents of the _fragments dir) are checked in so that we can avoid running the
shredder over the entire _examples dir each time someone refreshes the repo ( the shred-full gulp task).
The gulp serve-and-watch shredder is only a ‘partial’ shredder. It only shred’s files in directories changed during
the current session.
