How to use the class SecureArray? #80

How to use the class SecureArray? It is not seem in the document? I want to transfer a np.ndarray type to secure type, how can I do that?

It's best to look at a demo like demos/np_id3gini.py to see how to work with secure arrays. Also see the other demos listed in demos/np-run-all.sh

For a basic secure type like secint = mpc.SecInt() you can use b = secint.array(a) to convert a Numpy array a into a secret-shared version b, and then work with b using Numpy operations.

Thanks! I have another problem, the SecInt type is unhashable, but I want to use it as the key of a dict, How can I do?
