`ssm`	a `ssm` object, returned by `new_ssm`.
`approx`	character, approximation used to simulate `ssm`: `"ode"` deterministic approximation, based on Ordinary Differential Equations. `"sde"` diffusion approximation, based on Stochastic Differential Equations. `"psr"` Euler-multinomial approximation, based on Poisson process with Stochastic Rates.
`dt`	numeric, integration time step.
`id`	integer, unique integer identifier that will be appended to the output.
`root`	character, root path for output files (if any) (no trailing slash). If `NULL` (default), outputs are written in "your_model_path/the_name_of_the_wrapper".
`n_thread`	numeric, number of threads to be used. Default to 1. Use `"max"` to set it automatically to the number of cores available on the machine using `detectCores`.
`n_parts`	numeric, number of particles.
`start, end`	character, starting and ending date of model simulation (in `YYYY-MM-DD` format). Default to data range.
`eps_abs_integ`	numeric, absolute error for adaptive step-size control.
`eps_rel_integ`	numeric, relative error for adaptive step-size control.
`freeze_forcing`	character, freeze covariates to their value at specified date (in `YYYY-MM-DD` format).
`freq`	numeric, for simulations outside the data range, print the outputs (and reset incidences to 0 if any) every specified days.
`interpolator`	character, gsl interpolator for covariates
`verbose`	logical, print logs (verbose). Default to `FALSE`.
`warning`	logical, print warnings. Default to `FALSE`.
`no_dem_sto`	logical, turn off demographic stochasticity (if any). Default to `FALSE`.
`no_white_noise`	logical, turn off white noises (if any). Default to `FALSE`.
`no_diff`	logical, turn off diffusions (if any). Default to `FALSE`.
`traj`	logical, print the trajectories. Default to `TRUE`.
`hat`	logical, print the state estimates. Default to `FALSE`.
`seed_time`	logical, seed the random number generator with the current time. Default to `TRUE`.
