SOAPpy.Types.faultType: Cannot use object of type stdClass as array

Hi Chris!
The example from the website is buggy because the WSDL urls are not
correct...
$WSDL_AUTH = 'https://kasapi.kasserver.com/soap/wsdl/KasAuth.wsdl'
$WSDL_API ='https://kasapi.kasserver.com/soap/wsdl/KasApi.wsdl'
which I had replaced so far.
then you will see the results, even if the login and pass do not match.
I think for many python developers it might be really interesting to
know, WHAT A PHP ARRAY is in python in a SOAP environment.
