Split up the frame_order.pdb_model user function backend into three components.

The main _pdb_model() method now consists of calls to three new methods _pdb_ave_pos(),
_pdb_geometric_rep() and _pdb_distribution(). The _pdb_geometric_rep() method is simply the
contents of the old _pdb_model() method and the two other methods are currently stubs.

More changes to the frame_order.pdb_model user function.

The idea is that a 3D structure file of the domains moved to the average position will be created
using the new 'ave_pos_file' argument. The 'file' argument has been renamed to 'rep_file' as this
will simply contain the geometric object representation.

The frame order auto-analysis 'results_dir' argument is now used by the auto-analysis.

The frame order PDB representation and visualisation script are now created after optimisation.

This is for the frame order auto-analysis. The optimise() method has therefore been renamed to
nested_models() as it now does more than just optimisation.

Added a comment to the output from value.display and value.write to describe the parameter.

This idea is discussed at http://thread.gmane.org/gmane.science.nmr.relax.user/1428.

The idea is to take the parameter description from the specific analysis API and add it to the top
of the file or output. This is to help understand what the Rex value are. For example for the Rex
parameter the first line would be:

# Parameter description: Chemical exchange relaxation (sigma_ex = Rex / omega**2).

Created the Structure.test_read_merge system test to test a new concept - merging of structures.

The idea is to add the merge argument to the structure.read_pdb user function to allow two different
structures in two PDB files to be merged. This is useful if structures of individual domains have
have been solved separately and are located in two PDB files. Then with the merge flag, you will
not need to use and external program or hand edit PDB files to join them.

Added the merge flag to the structure.read_pdb user function.

This currently does nothing.

The merge flag for the structure.read_pdb user function is now propaged to the pack_structs() method.

This structure API method calls the ModelList.merge_item() method which is yet to be implemented.

The MolList.add_item() structural API method now returns the added molecule container.

This is used by the pack_structs() method to alias the molecule, and will be required when structure
merging is implemented.

Implemented the merging of structural objects.

This allows the merge flag of the structure.read_pdb user function to work.

Bug fix for the structural data consistency test in the pack_structs() structural API method.

The index was not correct causing failures in certain rare cases.

The printouts from the structure.read_pdb user function are now different with the merge flag set.

The text now says that the molecules are being merged rather than added.
