A list of attributes of the fitted model: mle (the maximum likelihood estimates of
the parameters of the model), data (the movement data), mod (the object
returned by the numerical optimizer nlm), conditions (a few conditions used to fit
the model: stepDist, angleDist, zeroInflation, estAngleMean,
stationary, and formula), rawCovs (optional – only if there are covariates
in the data).
