Contributes to #2407 - Dropped the “2” in “Angular 2” and “angular2_*” where appropriate. - Did a partial sync of `_cache/guide/pipes.jade` - In quickstart, changed `Try changing the message to "Hello Angular 2!”` to `Try changing the message to "Hello Again Angular!”`.
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.
