/**
 * Launches a clustered and load-balanced set of web servers.
 * Demonstrates syntax, so many of the options used here are the defaults.
 * (So the class could be much simpler, as in WebClusterExampleAlt.)
 * 
 * Requires: 
 * -Xmx512m -Xms128m -XX:MaxPermSize=256m
 * and brooklyn-all jar, and this jar or classes dir, on classpath.
 * 
 * @deprecated in 0.5; see {@link brooklyn.demo.WebClusterExample}
