[Soap-Python] soaplib 2.0.0beta documentation correction

[Dave Dodd]

Gday folks,

I have run into an error in the soaplib 2.0.0 beta documentation's examples
regarding Binary Files.

The first two examples on the page http://soaplib.github.com/soaplib/2_0/pages/binaryfiles.html fail with the following error reported:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: wrapper() takes at least 4 arguments (2 given)

I tried just executing:

>>> Attachment.to_parent_element(a)

And the same error is reported.  Can anyone clarify what is going on please ?
