 *	A sequence object has three components: i) an accession number / name, ii) the unaligned primary sequence, iii) a
 *	pairwise aligned sequence, and iv) a sequence that is aligned to a reference alignment.  This class has methods
 *	to set and get these values for the other classes where they are needed.  *
