Avoid using time-dependence of parameters in concentration computation
In ConcentrationModel
, the parameters (which are assumed to be constant for the formula to be valid) are computed only at the next state change.
Also providing the new methods (non public) _next_state_change
and _concentration_limit
- the latter improves code readability and will be useful for the integration of the concentration with an analytic formula.
