examples: Added 'Interesting' tag to examples

Browse Source 
* Added //! [Interesting] tag to all examples which were missing this
* Removed windows CR/LF
* Removed pointers from examples since these are not needed.  Removed
  try/catch which seems to be there only to handle failing pointers and
  return value from main.
* Reformatted examples when the formatting was wonky/inconstant.
