/**
 * TextAreaExpander plugin for jQuery
 * v1.0
 * Expands or contracts a textarea height depending on the
 * quatity of content entered by the user in the box.

 * Please use as you wish at your own risk.
 */

/**
 * Usage:
 *
 * From JavaScript, use:
 *	   $(<node>).TextAreaExpander(<minHeight>, <maxHeight>);
 *	   where:
 *		 <node> is the DOM node selector, e.g. "textarea"
 *		 <minHeight> is the minimum textarea height in pixels (optional)
 *		 <maxHeight> is the maximum textarea height in pixels (optional)
 *
 * Alternatively, in you HTML:
 *	   Assign a class of "expand" to any <textarea> tag.
 *	   e.g. <textarea name="textarea1" rows="3" cols="40" class="expand"></textarea>
 *
 *	   Or assign a class of "expandMIN-MAX" to set the <textarea> minimum and maximum height.
 *	   e.g. <textarea name="textarea1" rows="3" cols="40" class="expand50-200"></textarea>
 *	   The textarea will use an appropriate height between 50 and 200 pixels.

/**
 * Upgrades by Jon Gibbins
 * 26 Nov 2009	Now accepts minHeight and maxHeight
