*/
jQuery.fn.equalHeights = function(){
  var colSelector = this.selector;// Get the selector of the object
  var newHeight;
  var colHeights = [];
  $(colSelector).css('height', '');// Clear heights first
  $(colSelector).each(function(){
    var singleCol = $(this).outerHeight();// Get the outerHeight of a single column
    colHeights.push(singleCol);// Push the single height into the array
    newHeight = Math.max.apply(Math,colHeights);// Get the tallest column from the array
  });
  $(colSelector).css('height', newHeight+'px');// Apply the tallest height to all columns
}
