/**
 * The most common kind of controller; effectively a controller linked to a {@link DataObject}.
 *
 * ContentControllers are most useful in the content-focused areas of a site.  This is generally
 * the bulk of a site; however, they may be less appropriate in, for example, the user management
 * section of an application.
 *
 * On its own, content controller does very little.  Its constructor is passed a {@link DataObject}
 * which is stored in $this->dataRecord.  Any unrecognised method calls, for example, Title()
 * and Content(), will be passed along to the data record,
 *
 * Subclasses of ContentController are generally instantiated by ModelAsController; this will create
 * a controller based on the URLSegment action variable, by looking in the SiteTree table.
 *
 * @todo Can this be used for anything other than SiteTree controllers?
 *
 * @package cms
 * @subpackage control
