docstring: Safely trim a text.
  
  This method is HTML aware, it will not "destroy" any HTML tag. You can trim
  the text to a given number of characters, or you can give a string as second
  argument which will be used to cut the given text and return the first part.
  
  ## Examples:
  
  $text = '
  Lorem ipsum dolor sit amet, consectetur adipiscing elit.
  Fusce augue nulla, iaculis adipiscing risus sed, pharetra tempor risus.
  <!-- readmore -->
  Ut volutpat nisl enim, quic sit amet quam ut lacus condimentum volutpat in eu magna.
  Phasellus a dolor cursus, aliquam felis sit amet, feugiat orci. Donec vel consec.';
  
  echo $this->trimmer($text, '<!-- readmore -->');
  
  // outputs:
  Lorem ipsum dolor sit amet, consectetur adipiscing elit.
  Fusce augue nulla, iaculis adipiscing risus sed, pharetra tempor risus.
  
  echo $this->trimmer('Lorem ipsum dolor sit amet, consectetur adipiscing elit', 10);
  // out: "Lorem ipsu ..."
  
  @param string $text The text to trim
  @param string|int|false $len Either a string indicating where to cut the
  text, or a integer to trim text to that number of characters. If not given
  (false by default) text will be trimmed to 600 characters length.
  @param string $ellipsis Will be used as ending and appended to the trimmed
  string. Defaults to ` ...`
  @return string
