Add explicit testing to outbreak model #175
Description
Currently, the transmission model in {ringbp} assumes an infinite number of tests and that the test sensitivity is 100%.
In a fork of {ringbp} (https://github.com/timcdlucas/ringbp) there is explicit testing. From what I can see browsing the code, there is test sensitivity, parameterised by a user-defined argument, but still infinite testing capacity.
I believe it would be a good development and make the model more policy-focused by adding the ability to specify test sensitivity and testing capacity (e.g. maximum number of daily or weekly tests).
