[vtkusers] SetResliceAxesDirectionCosines

[David Gobbi]

Hi Sebastien,

The SetResliceAxesDirectionCosines() takes 3 vectors to make the
class more general, i.e. to allow a person to specify the x,y,z
axes of an output volume.  For a single slice, take the cross
product of the x and y vectors to get a z vector.  Then, use
SetResliceAxesOrigin() to specify a point that lies on the slice
plane.
