add_equilibrium

Fits a state-space mass-balance model for marine ecosystems,
which implements dynamics derived from
'Ecopath with Ecosim' <https://ecopath.org/>
while fitting to time-series of fishery catch, biomass indices,
age-composition samples, and weight-at-age data. Package
'ecostate' fits biological parameters (e.g., equilibrium mass)
and measurement parameters (e.g., catchability coefficients)
jointly with residual variation in process errors, and can include
Bayesian priors for parameters.
