Removed a useless junk script.

Added a directory and files for testing the white noise in relaxation data.

This includes scripts and graphs.

Added some more functions to the lib.statistics module.

These include the bucket() function for creating a discrete distribution from a list of floating
point numbers, and the gaussian() function for calculating the probability of a point on a Gaussian
distribution.

Expanded the relaxation dispersion auto-analysis.

A final step of model selection has been added to select between the different models for each spin
cluster. This is stored in the 'final' data pipe, and its results output via the write_results()
method.

Added support for model selection to the relaxation dispersion specific analysis package.

This involved redesigning the model_loop() method. Instead of yielding both the spin containers and
the spin IDs, now only spin IDs are yielded. This is important as the model loop is used
independently of the data pipes. Hence the spin containers cannot be yielded as multiple pipes are
compared within the model loop. The auxiliary method _spin_ids_to_containers(spin_ids) has been
added to obtain the list of spin containers from the list of spin IDs.

To support model selection, the methods duplicate_data(), model_desc() and model_statistics() have
been added, and model_type() aliased to the common _model_type_local() method.

Added two methods to the specific analysis common API class.

These are the _model_type_global() and _model_type_local() methods for always specifying that the
model type is global (i.e. at the level of the data pipe) or local (i.e. there can be multiple
clusters of models).

Added support for setting the spin isotope information in the dispersion GUI.

A new Text_ctrl element has been added just after the spin system GUI element. This displays a list
of all the spin isotopes currently defined and is updated after every GUI user function call. The
button of the element launches the spin.isotope user function.

The spin isotope information is now checked for prior to executing the GUI analysis and added to the
missing list to present to the user when blocking the execution of the analysis.

The dispersion GUI test has been updated to use this new element.

Fix for the lib.dispersion package __all__ list.

Fix for the lib.dispersion.equations.calc_two_point_r2eff_err() function.

The variables were incorrectly named.
