* DItemInfo is a class to get item information from host application (Showfoto or digiKam)
* The interface is re-implemented in host and depend how item information must be retrieved
* (from a database or by file metadata).
* The easy way to use this container is given below:
*
* // READ INFO FROM HOST ---------------------------------------------
*
* QUrl itemUrl; // The item url that you want to retrieve information.
* DInfoInterface* hostIface; // The host application interface instance.
*
* DInfoInterface::DInfoMap info = hostIface->itemInfo(itemUrl); // First stage is to get the information map from host application.
* DItemInfo item(info); // Second stage, is to create the DIntenInfo instance for this item by url.
* QString title = item.name(); // Now you can retrieve the title,
* QString description = item.comment(); // The comment,
* QDateTime time = item.dateTime(); // The time stamp, etc.
*
* // WRITE INFO TO HOST ----------------------------------------------
*
* QUrl itemUrl; // The item url that you want to retrieve information.
* DInfoInterface* hostIface; // The host application interface instance.
*
* DItemInfo item; // Create the DIntenInfo instance for this item with an empty internal info map.
* item.setRating(3); // Store rating to internal info map.
* item.setColorLabel(1); // Store color label to internal info map.
* hostIface->setItemInfo(url, item.infoMap()); // Update item information to host using internal info map.
