+The set axis method differs for the two interfaces. The cdunif method is straightforward and grabs an axis object direct from the file whereas the NAPPY method stores the name of the axis in a variable called self.axisstub for reference later - however to do this it has to get all the axes and then strip the units from them. This is confusing detail but the basic idea is to store 'something' that will give you a handle back to the axis. This something will be internal to the XYZInterface class.
