     *
     * To use, you should use the ContentItem subclass which

     * Because subsequent re-code generations will overwrite any changes to this
     * file, you should leave this file unaltered to prevent yourself from losing
     * any information or code changes.  All customizations should be done by
     * overriding existing or implementing new methods, properties and variables
     * in the ContentItem class.
