This will be used for expanding the functionality of the structure.align user function to perform
true sequence alignment via the new lib.sequence_alignment package. The test aligns 3 calmodulin
(CaM) structures from different organisms, hence the sequence numbering is different and the current
structure.align user function design fails. The structure.align user function has been expanded in
the test to include a number of arguments for advanced sequence alignment.
