/**
 * 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
 * Updated 06/15/2010 - Zach Lovelady - use outerHeight() intead of height()
 * Updated 06/17/2010 - Zach Lovelady - overflow goes to hidden instead of auto. Other 1px differences from
 *                      focus states, etc, were causing scrollbars.
 *
 * Copyright (c) 2008 Rob Glazebrook (cssnewbie.com) 
 *
 * Usage: $(object).equalHeights([minHeight], [maxHeight]);
 * 
 * Example 1: $(".cols").equalHeights(); Sets all columns to the same height.
 * Example 2: $(".cols").equalHeights(400); Sets all cols to at least 400px tall.
 * Example 3: $(".cols").equalHeights(100,300); Cols are at least 100 but no more
 * than 300 pixels tall. Elements with too much content will gain a scrollbar.
