    This is the wxTreeMultiCtrl documentation guide. For the upcoming CodeShop project I am working on, I've
    created a new control for wxWidgets (http://www.wxwidgets.com), with similar functionality as
    the wxTreeCtrl. This control allows you to add multiple wxWindow based components in a tree shaped form,
    with multiple root entries, which can contain multiple sub nodes, which can contain the visual controls
    in the tree. The tree behaves very much like a wxTreeCtrl, showing all controls in a more structured way.

    wxTreeMultiCtrl is freeware and distributed under the wxWidgets license. wxWidgets is THE toolkit for
    (cross platform) C++ / Python programming!

    \section how_work How does it work?

    The internals of the wxTreeMultiCtrl are built up from a composite pattern. This pattern forms a recursive
    tree where each end node can consist of a Window or a Node type. The Node type can consist out of multiple
    Window or Node types, and the  Window type is an end node which contains an assigned wxWindow to be displayed
    on the current level.

    The wxTreeMultiCtrl communicates to the developer by using the wxTreeMultiItem class, which is about the same
    as a wxTreeItemId. The wxTreeMultiItem class can be used in add or delete operations, fold operations, find
    operations, data get and set methods, and more. It helps the developer build up the tree, and later on,
    get and set data from it.

    \section what_dp What can it do and what not?

    What it can do:

    - Run-time addition / deletion of nodes, with an unlimited level depth
    - Inheriting the control makes it possible to respond to the events of the added wxWindow based components
    - Since all structured controls are owned by the wxTreeMultiCtrl, FindWindow will work, and all events can be captured
    - Collapsing and expanding of a (or all) sub nodes from a specific location by method or by mouse click
    - Typesafe getting or setting boolean, text or selection values by simply passing the window ID
    - Run-time adjustment of spacing between controls
    - Easy indenting of Window nodes
    - Contain complex controls per Window node by putting them on a wxPanel, allowing custom behavior of those controls on the wxPanel
    - Automatic deep background color adjustment of every window added, which means that every control on a wxPanel will be
      automatically set to the proper background. There is also an exception flag for wxButton controls, so that they remain
      their original color (if desired).

    What it cannot do:

    - Drag and drop support of individual nodes. Since the purpose was creating a tree shaped / property sheet kind of window,
      dragging and dropping is not really desired behavior.
    - No selection possible. Click on the controls to edit, double click on a container node to collapse and expand.
    - Draw a selection border. Since there is no selection possible, no selection will be drawn
    - Editing of captions like point and click in wxTreeCtrl. Again this is not desired behavior, because the (sub)
      items are not really the same as wxTreeCtrl items.

    Special thanks to Phil for testing, Julian Smart et al. for making this great toolkit!

/** \class wxTreeMultiItem
    \ingroup classes
    \brief An intermediate class which is used to return as 'item' value for the wxTreeMultiCtrl. This class
    is comparable with wxTreeItemId.

    The wxTreeMultiItem is used to pass information to the user about the tree node in question. It can also be used point out where the
    subnodes should be added.

    For example:
    \code

        wxTreeMultiItem item = MyMultiTreeCtrl->AddRoot("This is the first root");

        // now add a node to the root
        if(item.IsOk())
            MyMultiTreeCtrl->AppendWindow(item, new wxStaticText(MyMultiTreeCtrl, -1, "This is a static text");


    \endcode

    The wxTreeMultiItem comes in three internal types which are used in the wxTreeMultiCtrl. For functions such as
    wxTreeMultiCtrl::AddRoot, a Root item is returned. For functions such as wxTreeMultiCtrl::AppendWindow, a
    Window node is returned. For functions such as wxTreeMultiCtrl::AppendNode, a Node item is returned.

    \li A Root item represents a top level item. Special operations on this item is adding multiple nodes to it from a
    top level.

    \li A Node item represents a container item which has multiple sub items which can both be Window items, or Node items.
    A root item is a special type of Node item, so all operations which are only for Node items, are also for Root items.

    \li A Window node represents an end node, which points to a wxWindow which represents the visual contents of this node.
    This type of node can hold any wxWindow derived class.
