/**
 * This is a MODX snippet to add "new" or "Updated" images to menu,
 * pages and such.
 * You need to provide your own new.gif and updated.gif file. change the
 * file path to the images files accordingly.
 * if called without input parameter then it will look at the page resource and
 * determine if the page is newly published or updated.
 * if called with input=`resourceID` then it will look into that resource ID.
 * This snippet can be also used with getResoruces or Wayfinder.
 * To indicate if the page is new or updated, then simply call
 * [[!newOrUpdate]] in the page
 * To use with Wayfinder,
 * Wayfinder template should include [[!newOrUpdate? &input=`[[+wf.docit]]`]]
 * therefore,  rowTpl can be defined like this
 * <li [[+wf.id]] [[+wf.classes]] >
 * <a href="[[+wf.link]]" title="[[+wf.title]]" [[+wf.attributes]]>
 * [[+wf.linktext]][[!newOrUpdate? input=`[[+wf.docid]]`]]</a> [[+wf.wrapper]]
 * </li>
 * and wayfinder snippet will be called like this
 * [[!Wayfinder? &rowTpl=`rowTpl`]]
 * To use with getResources..
 * getResources template should include [[!newOrUpdate? &input=`[[+id]]`]]
 * therefore, the template can be defined like so..
 * <dt>
 * <a href="[[~[[+id]]]]">[[+pagetitle]]</a>[[!NewOrUpdate? input=`[[+id]]`]]
 * <dd>
 * [[+longtitle]]</br>
 * [[+introtext]]
 * </dd>
 * </dt>
