Added a function to determine how to nest/copy the parameters, when nesting from another model.

It takes the list of parameters from the current model, and the list of parameters available in the nested model,
and return a dictionary of parameter conversion for the current model params.

Added a relaxation dispersion example to show how certain literature statements are just utter crap!

This follows from http://thread.gmane.org/gmane.science.nmr.relax.scm/22774/focus=6693, and the
commit r25024 (http://thread.gmane.org/gmane.science.nmr.relax.scm/22774) which implement such
dangerous literature conjectures. To see how a real minimum is excluded from the optimisation
space, here for residue :2, execute the R1rho_analysis.py script in relax.

This is synthetic data generated with kex = 1e5 assuming the model TP02. For the case of residue
:2, this still produces an optimisable minimum in the space and dispersion curves. However r25024
blocks optimisation to the minimum.

Added initial python script, to help print each model and its corresponding nested models.

It can be executed by:
relax test_suite/shared_data/dispersion/print_model_info/print_model_info.py

Modified nesting function, to pull list of possible models from dictionary, and check if these models are
available in the completed models.

Modified unit test regarding finding correct nested model.

Modified the defined list of nesting, according to thread:

Added the ordered list of nest models to the class of model information.

Division of unit tests of specific_analyses/relax_disp/model.py into different functions.

Also added more print information to each tests.

Moved the lookup in dictionarys for model information, into the class of model info.

Added definition and dictionary, for each model, to determine which model they nest from.

This is better to Hard-code, since it makes it possible to produce a table with an overview,
and accurately determine which model is nested from.

This is discussed in thread.
