All '/resources' URLs are resolved by Spring JavaScript's the ResourceServlet configured in the web.xml.
<link type="text/css" rel="stylesheet" href="<c:url value="/resources/dijit/themes/tundra/tundra.css" />" />
<script type="text/javascript" src="<c:url value="/resources/dojo/dojo.js" />"></script>
<script type="text/javascript" src="<c:url value="/resources/spring/Spring.js" />"></script>
<script type="text/javascript" src="<c:url value="/resources/spring/Spring-Dojo.js" />"></script>
The create link goes to '/person.html' which is mapped to the person flow. The search link still goes through the PersonController.
Both the create and search links are secured so when the login and logout pages are rendered, these links aren't displayed until
the user logs in.

The edit link goes to the person flow (ex: '/person.html?id=1'). The flow will look up the person record based on the id request parameter.

The form:form element just needs to have it's modelAttribute set to correspond to where the flow put
the Person instance. The save and cancel buttons specify which event id they are associated with for this step in the flow.
This value should match the flow's transition element's on attribute.
Messages are displayed at the top if there are any status or error messages available. Basic validation is performed
by the PersonValidator. Which just checks that something has been filled in for the first and last name.
