Provide dynamic data sorting and grouping using the GroupDescriptions property.

The sample contains a tab control with two pages:

The first tab page demonstrates how to group data contained in a DataTable using 
the grid's new GroupDescriptions property. Buttons along the top of the grid allow 
you to select the grouping criteria and whether to hide columns being grouped by
to present compact views of the data.

The second tab page does the same thing using a SortableBindingList which wraps 
a simple collection of arbitrary objects. The SortableBindingList is included in 
the C1.Win.C1FlexGrid assembly and provides advanced sorting support not available
in the standard .NET BindingList class.

The grid columns use the new StarWidth property to fill the grid width according
to given proportions (star sizes).
