Summary:                    Expose CellLocators in widgets
Description: 
It would be nice if the cell locator(s) were accessible from the widgets (e.g.
vtkPlaneWidget, vtkBoxWidget, vtkSplineWidget , etc.).

This would allow to observe 'PickEvents' in codes using these widgets. I would
like to attach a custom callback to these events, but cannot obtain a reference
to the locator, which invokes them.

A simple API change would include the functions:

	// Description:
	// Get picker used for handles, e.g. if you want to observe events from
	// this picker
	vtkGetObjectMacro(HandlePicker,vtkCellPicker);

	// Description:
	// Get picker used for handles (See GetHandlePicker() ).
	vtkGetObjectMacro(ControlPicker,vtkCellPicker);
