recovery rate calculation

[jzanetti]

Hi JUNE developers:

There are lines of codes defining the probability of person who recovers in the ward (see Link for details), for example,

p[population][sex][age][3] = (
    hospital_rate - hospital_dead_rate
)

Should the max function be applied to ensure that the recovery rate is larger than zero ? For example,

p[population][sex][age][3] = max(
    hospital_rate - hospital_dead_rate, 0
) 

Thank you,

Sijin
