added an example showing bidirectional binding between python/react for complex objects

[paddymul]

bi-directional binding between jupyter and python works... as long as you replace the entire object from both sides. As is react best practice.

and one more observation: when I change the parameter bar in the second example

z = UpdateDictFromReactWidget()
z.simple_dict["bar"] = 3000

bar does not update to 3000 as well when I press the increment bar button. bar only gets the new value after pressing the times confetti button. As before, z.simple_dict = {'foo':2, 'bar':2, 'baz':2} updates everything immediately.

Note that trailets doesn’t detect mutations of objects, only assignment. This reflect the Python language. Not something we can change I think.
