MYZ_dts - Implement the dawn-day-dusk-night model

[smitdave]

A runtime mismatch is when two different dynamical components run at different time steps. For example, suppose_ that we want to run a model for humans that updates once every 7 days, but we want to run a model for mosquitoes that updates four times a day (dawn, day, dusk, night).

Note that this challenge is unique to discrete-time systems.

For fine-grained simulations that work on time steps less than one day, a solution was developed in the ENBQR model that internalizes computation of fqZ. A problem with this is that for internal consistency, each time step would need its own TaR matrix, and the EIR would need all fqZ values. Hmmm.
