Related Issue:

The code of the two routers look very similar whilst they are calling differnt objects.

Proposed Changes

• A facade is added to the integrators
  • The client, router, has only to call the integrator and interact with its interface
  • The router codes could later be refactored as they are using a similar strutcure
