A simple calculation for the effective \(R_\text{eff}\), allowing for heterogeneity in social contacts and the proportion of each age group remaining susceptible. This assumes a single susceptible stratum with full susceptibility, and will be updated in future versions to account for the addition of vaccination strata with reduced susceptibility.
