/**
* 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) 
*
* 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.
*
