Add support for numpy arrays

Make compatible with json_tricks numpy handling (#6)

Added support for handling np.ndarrays in the json_tricks style. We can load files written by json_tricks and write files that are compatible with it. I also copied over the sparse matrix handler from core.

Introduces YAML safe loading and dumping

For backward compatibility, loading or dumping unsafe YAML contents only produce a DeprecationWarning if the function has not been explicitly called with a safe argument.

Loading or dumping with safe=False causes behavior identical to releases predating this one.
Loading or dumping with safe=True will ensure that only safe contents are allowed. Contents deemed unsafe by the pyyaml module will raise a SerializationSafetyError.
