WIP: Dag generator
I have proposed some changes to the qiskit SDK that will speed up our functionality which interfaces with DAGCircuit.layers()
quite a bit. This branch uses those changes.
Don't merge until qiskit has been updated to support the changes. Or implement the functionality ourself.
See: https://github.com/QISKit/qiskit-sdk-py/pull/378 https://github.com/QISKit/qiskit-sdk-py/pull/371
