Created a new structural API method, pack_structs().

This has the fun job of mapping the original models and molecules of the PDB (or which ever other
file format is read in the future) into the models and molecules stored within relax. I.e.
molecules can be converted to models and vice versa.

Added a missing quote which prevented the user manual to be sconstructed.

This was spotted in r8433 and discussed in a thread starting at:

Redesigned the Scientific python structural object load_pdb() method.

The structural data structure is not yet created.

Imported relaxation dispersion in grace user functions.

However, there is now a problem when constructing the manual (scons user_manual_pdf), in the latex
part of the code, where the following error message is thrown:

Any ideas ?

Fixes for the __compare_objects() method.

Fixes for the duplicate_data() method.

Completed the scaling matrix code.

This follows a thread at:
https://mail.gna.org/public/relax-devel/2009-01/msg00073.html
(Message-id: <496C09F1.1000307@...>)

Started to implement the scaling matrix for scaling the 'R2eff' values.

This might change in the future as other possible curve fitting parameters ('R2', 'Rex', 'kex',
'R2A', 'kA', 'dw') might need some scaling.
