/**
 * JSP tag handler to show the current item within a show:list
 * or show:table tag.  For aesthetics in naming it may be mapped to
 * more than one JSP tag.
 *
 * <p>
 * sample Usage:
 *  <pre>
 * &lt;show:list name="mylist">
 *    show list item here <show:listItem/>
 * &lt;show:list name="mylist">
 * </pre>
 *
 *  <pre>
 * &lt;show:row name="mylist">
 *    show table column value <show:col/>
 * &lt;show:row name="mylist">
 * </pre>
 *
 * This has the effect of locally-styling the list contents in the JSP,
 * while globally styling the individual item inside the list.
