This should be run prior to any step functions to update
components over a time step. It computes various quantities related to
disease transmission between species using the generic interfaces (methods)
provided by each component. It updates h, vectors giving per-capita force
of infection for the bird and human components, and kappa, the net infectiousness
of hosts for the mosquito component.
