Deprecated way of setting options

[Ye2018]

For the snippet:

# Set the backend options, method set to statevector
options = {'method': 'statevector', 'memory':True, 'shots':10}

, putting options in a dictionary doesn't work anymore.
It should be:

#options = {'method': 'statevector', 'memory': True, 'shots': 10}
options = {"method": "statevector"}
# Execute circuit using the backend options created
job = execute(qc, backend_simulator, backend_options=options, memory=True, shots=10)
