/**
 * Provides a list effect that collapses the list and appends the number of list items to the remaining label.
 * Assumes that list items will be wrapped in a list break tag such as <li>.
 * Assumes that lists will have tagged labels.
 * Operative class should be assigned to the ul element of the list, nested elements will not be reflected in the element count.
 *
 * @example html:
 *
 *      <h3>A Link List</h3>
 *        <ul class="linklist">
 *         <li> Link 1 </li>
 *         <li> Link 2 </li>
 *        </ul>
 *
 * @example $('.linklist').listeffect('open' , .69)
 * @result A list open on page load that when clicked will collapse and append the list item number, and reduce text opacity to .69
 *
 * @example $('.linklist').listeffect(.69)
 * @result A list collapsed on page load (default) with appended list item number, and reduced text opacity to .69
 *
 * Options include list open or collapsed on page load, label text opacity setting between 0 and 1
