The $variables() method of a CmdStanModel object returns
a list, each element representing a Stan model block: data, parameters,
transformed_parameters and generated_quantities.
Each element contains a list of variables, with each variables represented
as a list with infromation on its scalar type (real or int) and
number of dimensions.
transformed data is not included, as variables in that block are not
part of the model's input or output.
variables()The $variables() returns a list with information on input and
output variables for each of the Stan model blocks.
