This is a minor feature and bugfix release. It includes the addition of the new
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 structure.align, structure.atomic_fluctuations,
structure.com, structure.displacement, structure.find_pivot, structure.mean, structure.rmsd,
structure.superimpose and 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
default to a residue number based alignment if the structure.sequence_alignment user function has
not been used. This version also fixes a system test failure on Mac OS X and Iinf parameter text
files and Grace graphs are produced by the relaxation curve-fitting auto-analysis for the inversion
recovery and saturation recovery experiment types.
