/*
truncates elements that pass a certain height.
adds a "view more" link to display the rest of the content.

a different approach than standard truncation which relies on character counting.
character counting may not be desireable when elements have short words, but a
number of line breaks.

usage:
  //using defaults
  $('css_expression').summary();
  
  //overriding options
  $('css_expression').summary({maxHeight: 200, className: 'view-more'});
