It added directories starting with '.' to the path. When I changed  
directory it could no longer find the paths, at least this is my guess  
at what is happening from the load path errors I am getting. I've  
checked and Matlab exhibits the same behaviour if you add relative  
paths, then change directory. addpath didn't do anything incorrectly,  
it did exactly what I asked, but I was asking something slightly silly.

However, further to this, I think there really is still some kind of  
issue with package folders in classdef, if I correctly add the package  
directory, I get issues:
