/**
* Equal Heights Plugin
* Equalize the heights of elements. Great for columns or any elements
* that need to be the same size (floats, etc).
* 
* Version 1.0
* Updated 12/10/2008
*
* Copyright (c) 2008 Rob Glazebrook (cssnewbie.com) 
*
* Revision: 1/14/2009, Jamie Krug
* Changed signature to accept one optional argument (options) as an associative array to better support more optional "arguments" in a more readable fashion.
* Added overflow option, to override default CSS declaration.
* Added addToHeight option, to optionally pad tallest height (can be used as a quick fix in quirky situations where a couple extra pixels will avoid overflow).
*
* Example 1: $(".cols").equalHeights();
* Example 2: $(".cols").equalHeights( { minHeight: 400 } );
* Example 3: $(".cols").equalHeights( { minHeight: 100, maxHeight: 300 } );
* Example 4: $(".cols").equalHeights( { overflow: 'visible' } );
* Example 5: $(".cols").equalHeights( { addToHeight: 3 } );
*
