The grid search setup function now prints out the grid search bounds to be used.

This is in the pipe_control.minimise.grid_setup() function, hence it is analysis independent. This
is useful feedback for the user to know what the grid search is doing. And it will be even more
useful for the zooming grid search to understand what is happening.

Fixes for the grid search backend for a recent breakage and expansion of its capabilities.

The user supplied lower and upper bounds for the grid search were no longer being scaled via the
scaling matrix.

In addition, the code has been refactored to be simpler and more flexible. The user can now supply
just the lower or just the upper bounds and the grid search will work.

More fixes for the elminate user function backend.

This is for the model_info argument changes in the specific API.

The new pipe_control.minimise module functions can now handle models with no parameters.

The new assemble_scaling_matrix() and grid_setup() functions will now handle models with no
parameters, as this is required for the relaxation dispersion analysis.

Updated the elminate user function backend to work with the model_info argument changes in the specific API.

Updated the frame order optimisation results for the CaM pseudo-ellipse test data.

The optimisation in the frame_order.py is now of higher precision with the number of Sobol' numeric
integration points significantly increased, especially for the Monte Carlo simulations. The new
frame order representation files have been added to the repository, as well as the intermediate
state files.

Updated the frame order optimisation results for the 2nd CaM free rotor isotropic cone test data.

The optimisation in the frame_order.py is now of higher precision with the number of Sobol' numeric
integration points significantly increased, especially for the Monte Carlo simulations. The new
frame order representation files have been added to the repository, as well as the intermediate
state files.

Fixes for the _data_init_spin() specific API common method.

The data returned from _base_data_loop_spin() is just the spin ID, the spin container is not
included.

Updated all of the data_init() specific API calls where the spin ID is expected.

More fixes for the Monte Carlo simulations for the model_info argument changes in the specific API.
