      Description

      In the current integrators, the coupling has been evaluated only once per step, while the Heun method should evaluate it twice. For many models, this isn't an issue, but some models have highly nonlinear coupling functions (e.g. Kuramoto) and convergence suffers significantly compared to custom code (10x smaller time step required). This will require a change to data flow as the integrator does not currently receive the coupling function instance as an argument.
