The spectrum.peak_intensities is now more robust when reading in a generic formatted file.

Firstly there is a check that the intensity column number has been supplied. And then there is a
checks that all relevant data could be extracted from each row of the file. This replaces traceback
errors with RelaxErrors explaining the problem if the user inputs bad data or forgets the intensity
column argument.

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.

The initial parameters are now the real parameter rather than the optimised ones.

This is for the script for testing white noise in relaxation data.

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.
