+ * # Overriding Own gui objects.
+ *
+ * The gui objct contains base properties for drow objects on scane
+ * * position
+ * * ratation
+ * * mash
+ * * and map textures
+ *
+ * All properies implemented on the GraphicItem.qml file.

+ *
+ * ### Example:
+ *
+ * Create a new qml file **OwnView.qml**
+ * ```qml
+ *  import CrawlModule 1.0
+ *
+ *  GraphicItem {
+ *      // your own implementation
+ *  }
+ * ```
+ *
+ * Override property in cpp object.
+ *
+ * ```cpp
+ * class MyObject: public IWorldItem {
+ *     MyObject(): IWorldItem("name", "qrc:/path/to/OwnView.qml") {
+ *     }
+ * }
+ * ```
