* Utility class representing links to different views of a record

* for CMS authors, usually for {@link SiteTree} objects with "stage" and "live" links.
|
||||
* Useful both in the CMS and alongside the page template (for logged in authors).
|

* The class can be used for any {@link DataObject} subclass implementing the {@link CMSPreviewable} interface.
|

*
|

* New item types can be defined by extending the {@link SilverStripeNavigatorItem} class,
|

* for example the "cmsworkflow" module defines a new "future state" item with a date selector
