1 2	create_fit_object(model.fit, model_alg, fitfunname, params, coef, nobs, model_contrl, fitclass = "H2Omodel", ...)

`model.fit`	Model fit object
`model_alg`	Name of the model algorithm
`fitfunname`	The name of the main function used for fitting (e.g., "glm")
`params`	List of main model parameters
`coef`	Fitted glm coefficients, if used
`nobs`	Number of observations used for fitting the model
`model_contrl`	Full list of model control parameters used
`fitclass`	The name of the R6 object class used for fitting
`...`	Additional objects that will be included in the final fit list
