/**
    @class wxGrid

    wxGrid and its related classes are used for displaying and editing tabular
    data.
    They provide a rich set of features for display, editing, and interacting
    with a variety of data sources. For simple applications, and to help you
    get started, wxGrid is the only class you need to refer to directly. It
    will set up default instances of the other classes and manage them for you.
    For more complex applications you can derive your own classes for custom
    grid views, grid data tables, cell editors and renderers. The @ref
    overview_gridoverview has examples of simple and more complex applications,
    explains the relationship between the various grid classes and has a
    summary of the keyboard shortcuts and mouse functions provided by wxGrid.

    wxGrid has been greatly expanded and redesigned for wxWidgets 2.2 onwards.
    The new grid classes are reasonably backward-compatible but there are some
    exceptions. There are also easier ways of doing many things compared to the
    previous implementation.

    A wxGridTableBase class holds the actual data to be displayed by a wxGrid
    class. One or more wxGrid classes may act as a view for one table class.
    The default table class is called wxGridStringTable and holds an array of
    strings. An instance of such a class is created by wxGrid::CreateGrid.

    wxGridCellRenderer is the abstract base class for rendereing contents in a
    cell. The following renderers are predefined:
     - wxGridCellStringRenderer,
     - wxGridCellBoolRenderer,
     - wxGridCellFloatRenderer,
     - wxGridCellNumberRenderer.
    The look of a cell can be further defined using wxGridCellAttr. An object
    of this type may be returned by wxGridTableBase::GetAttr.

    wxGridCellEditor is the abstract base class for editing the value of a
    cell. The following editors are predefined:
     - wxGridCellTextEditor
     - wxGridCellBoolEditor
     - wxGridCellChoiceEditor
     - wxGridCellNumberEditor.

        Register a new data type.

        The data types allow to naturally associate specific renderers and

        wxGRID_VALUE_STRING which uses wxGridCellStringRenderer and
        wxGridCellTextEditor as its renderer and editor respectively -- this is
        the data type used by all the cells of the default wxGridStringTable,
        so this renderer and editor are used by default for all grid cells.

        However if a custom table returns @c wxGRID_VALUE_BOOL from its
        wxGridTableBase::GetTypeName() method, then wxGridCellBoolRenderer and
        wxGridCellBoolEditor are used for it because the grid also registers a
        boolean data type with this name.

        And as this mechanism is completely generic, you may register your own
        data types using your own custom renderers and editors. Just remember
        that the table must identify a cell as being of the given type for them
        to be used for this cell.

        @param typeName

            wxGRID_VALUE_BOOL, @c wxGRID_VALUE_NUMBER, @c wxGRID_VALUE_FLOAT
            and @c wxGRID_VALUE_CHOICE), then the new registration information
            replaces the previously used renderer and editor.
        @param renderer
            The renderer to use for the cells of this type. Its ownership is
            taken by the grid, i.e. it will call DecRef() on this pointer when
            it doesn't need it any longer.

    with a grid which would otherwise result in flicker. For example:

    @code
    void MyFrame::Foo()
        {

            m_grid-AppendRow();

            // destructor called, grid refreshed
        }
    @endcode
