Deleted the SpecificData container as nothing now uses it.

Changed the 3D structure data structure from a SpecificData class to the Element class.

Removed an unused import of SpecificData.

Updated all the tests of the read_pdb() function to the new relax design.

Removed all references to 'self' from the generic_fns.structure module.

The args of the read_pdb() fn are no longer placed into self.

Converted all methods in the Structure class into functions of the generic_fns.structure module.

Removed a junk comment.

Reverted r4850 as generic_fns.value.partition_params() has returned to its previous behaviour.

The command used was:
svn merge -r4850:4849 .

When None, the param variable is converted to a list of None with the length equal to that of val.

This affects the generic_fns.value.set() function when no parameters are supplied.

Bug fix for the generic_fns.value.set() function.

The differentiation between a spin specific parameter and a global parameter was not working for
specific analyses with no spin specific parameters. The return_data_name() function was being used
to differentiate, which makes no sense. So instead the is_spin_param() function has been introduced
to allow the specific code to answer the question explicitly. Note that this will temporarily break
many things.

This function always returns true.
