/**
* \brief QtiPlot's main window.
*
* This class contains the main part of the user interface as well as the central project management facilities.
*
* It manages all MdiSubWindow MDI Windows in a project, knows about their organization in Folder objects
* and contains the parts of the project explorer not implemented in Folder, FolderListItem or FolderListView.
*
* Furthermore, it is responsible for displaying most MDI Windows' context menus and opening all sorts of dialogs.
*
* \section future Future Plans
* Split out the project management part into a new Project class.
* If MdiSubWindow maintains a reference to its parent Project, it should be possible to have its subclasses
* display their own context menus and dialogs.
* This is necessary for implementing new plot types or even completely new MdiSubWindow subclasses in plug-ins.
* It will also make ApplicationWindow more manageable by removing those parts not directly related to the main window.
*
* Project would also take care of basic project file reading/writing (using Qt's XML framework), but delegate most of
* the work to MdiSubWindow and its subclasses. This is necessary for providing save/restore of classes implemented in
* plug-ins. Support for foreign formats on the other hand could go into import/export classes (which could also be
* implemented in plug-ins). Those would interface directly with Project and the MyWidgets it manages. Thus, in addition
* to supporting QtXML-based save/restore, Project, MdiSubWindow and subclasses will also have to provide generalized
* save/restore methods/constructors.
*
* Maybe split out the project explorer into a new ProjectExplorer class, depending on how much code is left
* in ApplicationWindow after the above reorganizations. Think about whether a Model/View approach can be
* used for Project/ProjectExplorer.
