These functions are used to filter succesful model fits from those that errored or gave warnings.

is_ok(): returns rows from an <incidence2_fit> object that did not
error (and optionally produce a warning).
is_error(): returns rows from an <incidence2_fit> object that errored.
is_warning(): returns rows from an <incidence2_fit> object that
produced warnings.
The output of function fit_curve().
Not currently used.
Include results in output that triggered warnings but
not errors. Defaults to FALSE.
