dwave-system is a basic API for easily incorporating the D-Wave system as a sampler in the Ocean software stack, directly or through Leap service's cloud-based hybrid solvers. It includes DWaveSampler, a dimod sampler that accepts and passes system parameters such as system identification and authentication down the stack, LeapHybridSampler, for Leap's hybrid solvers, and others. It also includes several useful composites---layers of pre- and post-processing---that can be used with DWaveSampler to handle minor-embedding, optimize chain strength, etc.
