examples.py broken ('Order' object has no attribute 'ensure_subproducts')

[jmtd]

After substituting some real credentials, with a clone of the repo (thus current master):

$ python examples.py
Traceback (most recent call last):
  File "examples.py", line 21, in <module>
    order.ensure_subproducts()
AttributeError: 'Order' object has no attribute 'ensure_subproducts'

Did you leave the default login credentials in examples.py? Trying to reproduce.

No, I substituted them for my real credentials.
