SEIRComponent
final class SEIRComponent
SEIR (susceptible-exposed-infectious-recovered) reusable component. Two such components are assembled into a vector-borne-disease model, one to represent the human population, and one for the mosquito population.

Member Function Details
transfer
function transfer(t:Integer, τ:Integer)
Transfer between compartments.
- t: Step number.
- τ: Number of trials that may result in exposure.
τ is computed externally according to the interaction between two
populations, then transfer() called to update the state of the
population.
