Random iterate taglib ver. 1.3

Custom JSP tag. Lets you iterate execution over the random subset of collections, iterators, enumerations or arrays. For example:

<%@ taglib uri="taglib.tld" prefix="loop" %>

<%
  java.util.Vector v=new java.util.Vector();
  v.addElement("first");
  v.addElement("second");
...
%>

<loop:randomIterate source="<%=v%>" id="A" count="5">
<br>Element: <%=A%>
</loop:randomIterate>

Here tag executes own body for the 5 random elements from the source.
