* Initialised the lib.structure package - this is currently empty.
* Shifted the rotor creation components from generic_fns.structure.geometric to lib.structure.rotor. The create_rotor_pdb() function remains in place as this is the user function backend which checks for data pipes and updates the status object, but the rotor_pdb() and create_rotor_propellers() functions have been moved into the relax library. The create_rotor_propellers() function has been renamed to lib.structure.rotor.rotor_propellers().
* Converted links in all docstrings to use the Epydoc hyperlink notation. This will allow links to be clickable for the API documentation ([http://www.nmr-relax.com/api/)API documentation].* Added Epydoc hyperlink markup for the bug tracker in the system test docstring where missing. This is for a better API documentation ([http://www.nmr-relax.com/api/)API documentation].
* The lib.structure.rotor.rotor_pdb() rotor_angle argument should now be in radians. This does not affect the structure.create_rotor_pdb() user function as the generic_fns.structure.geometric.create_rotor_pdb() function converts the value to radians prior to calling the rotor_pdb() function.
* The lib.structure.rotor.rotor_pdb() function can now handle structural models. The model number argument has been added to allow the rotor structure to be added to a single model, or to all models if not supplied.
