+/**
+ * \ingroup org_mitk_gui_qt_welcomescreen_internal
+ * \brief QmitkMitkWorkbenchIntroPart
+ * The WelcomeView Module is an helpful feature to people new to MITK. The main idea is to provide first 
+ * information about the MITK Workbench. 
+ * The WelcomeView is realized by making use of the QTWebKit Module. The Qt WebKit module 
+ * provides an HTML browser engine that makes it easy to embed web content into native applications, and to enhance 
+ * web content with native controls.
+ * For the welcome view of the application the QWebView, QWebPage classes have been used. The shown WelcomeView
+ * html start page is styled by an external css stylesheet. The required resources as well as the html pages are integrated 
+ * into the QtResource system. The QT resource system allows the storage of files like html pages, css pages, jpgs etc. 
+ * as binaries within the executable. 
+ * This minimizes the risk of loosing resource files as well as the risk of getting files deleted. In order to use the Qt 
+ * resource system the resource files have to be added to the associated qrt resource file list. 
+ * 
+ * The foundation is set to design more complex html pages. The Q::WebPage gives options to set a 
+ * LinkDelegationPolicy. The used policy defines how links to external or internal resources are handled. To fit our needs 
+ * the delegate all links policy is used. This requires all external as well as internal links of the html pages to be handle 
+ * explicitly. In order to change mitk working modes (perspectives) a mitk url scheme has been designed. The url scheme 
+ * is set to mitk. The url host provides information about what's next to do. In our case, the case of switching to a 
+ * particular working mode the host is set to perspectives. The followed path provides information about the perspective id.
+ * (e.g. mitk//::mitk.perspectives/org.mitk.qt.defaultperspective) The the generic design of the mitk url scheme allows to  
+ * execute other task depending on the mitk url host.
