One question regarding the interface of initial mapper. Should we instead expose a method that expects a circuit or a (circuti, device_graph) and returns an initial mapping for that circuit / circuit, device graph combination?
I'm thinking that the class should encapsulate the strategy to map a circuit on a device; and not necessarily hardcode exact circuit / device combination as part of it's construction.

Can we rebase it to master so that unrelated changes in mapping manager don't appear here? We can merge once it's rebased.
