/**
 * <p>Title: Represents an entry in the content cache.</p>
 * <p>Description: The purpose of this object is to offer not just content
 * cache but also to offer the possibility to add meta-data to this content.
 * In order to do this all the content is stored in a Property table.</p>
 * <p>This class offers default properties such as contentType, contentData,
 * lastAccessDate and hits but also offers a generic hash map to extend the
 * possibilities of using meta-data for a cache entry.</p>
