  /**
   * 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.
