如何在MATLAB中使用python词典对象？

I'm playing with the new capability in MATLAB 2014b where you can call python directly from matlab and get python objects in the workspace (like you've been able to with Java for a long time). I have successfully called a function and gotten a dictionary into the workspace, but I'm stuck on how to harvest the values from it. In this case I have a dictionary full of dictionaries, so I can't just convert it to MATLAB cells like they do in their example.I'm playing with the new capability in MATLAB 2
