+/**
+* This is FileTree widget for listing files belonging to the project. It does feature:
+* - dynamic updates reflecting the state of the project dir and subdirs
+* - VCS support for showing VCS fields like state, working and repository revisions
+* - bolding the filenames belonging to project to distinguish them from the others
+* - dynamic filtering so the user has not to care about temporary files eating screen space ;-)
+*
+* Design notes
+* The class uses two different implementations (referred by m_impl data member):
+* - @see VCSFileTreeWidgetImpl for VCS support
+* VCS support is detencted by the constructor looking for the @see KDevPlugin::versionControl() member:
+* if the current VCS plug-in does offer a @see KDevVCSFileInfoProvider object than this will be used for
+* querying about files' data. If neither VCS plugin nor valid info provider is found then the filetreeview
+* will fallback to the standard implementation
+* - @see StdFileTreeWidgetImpl for standard visualization, just like the KFileTreeView
+*
+* Each implementation must provide a branch item factory which the file filetree will delegate the creation
+* of specific KFileTreeViewItem-derived objects: currently they are both defined in the same .h/.cpp files
+* of the implementations listed above.
