The parameter object now registers the grid bounds and scaling factors for all of the N-state model
parameters.

The specific_analyses.n_state_model.parameters.assemble_scaling_matrix() function has been deleted
as this is now provided by the upstream code in pipe_control.minimise. And the API methods
grid_search() and minimise() has been modified to accept the list of scaling matrices. In addition,
all of the lower bounds defined in the grid_search() API method have been deleted as this is now in
the parameter object.

The new API function print_model_title() has been aliased from _print_model_title_global(). And the
get_param_names() and get_param_values() API methods have been implemented.
