Resizable button to be used in a Tk::HList column header

The ResizeButton widget provides a resizeable button widget for use in an HList column header. When placed in the column header, the edge of the widget can be selected and dragged to a new location to change the size of the HList column. When resizing the column, a column bar will also be placed over the HList indicating the eventual size of the HList column. A command can also be bound to the button to do things like sorting the column.
