Changes

This is a minor feature and bugfix release. It includes the addition of the new [http://www.nmr-relax.com/manual/structure_sequence_alignment.html structure.sequence_alignment user function] which can use the 'Central Star' multiple sequence alignment algorithm or align based on residue numbers, saving the results in the relax data store. The assembly of structural coordinates used by the [http://www.nmr-relax.com/manual/structure_align.html structure.align], [http://www.nmr-relax.com/manual/structure_atomic_fluctuations.html structure.atomic_fluctuations], [http://www.nmr-relax.com/manual/structure_com.html structure.com], [http://www.nmr-relax.com/manual/structure_displacement.html structure.displacement], [http://www.nmr-relax.com/manual/structure_find_pivot.html structure.find_pivot], [http://www.nmr-relax.com/manual/structure_mean.html structure.mean], [http://www.nmr-relax.com/manual/structure_rmsd.html structure.rmsd], [http://www.nmr-relax.com/manual/structure_superimpose.html structure.superimpose] and [http://www.nmr-relax.com/manual/structure_web_of_motion.html structure.web_of_motion] user functions has been redesigned around this new user function. It will use any pre-existing sequence alignments for the molecules of interest, but use no sequence alignment if only structural models are selected, and default to a residue number based alignment if the [http://www.nmr-relax.com/manual/structure_sequence_alignment.html structure.sequence_alignment user function] has not been used. This version also fixes a system test failure on Mac OS X and I_∞ parameter text files and Grace graphs are produced by the relaxation curve-fitting auto-analysis for the inversion recovery and saturation recovery experiment types.
