#1 NeedlemanWunschGotoh sequence order is not consistent

[Jared R. White]

Hello there.

NeedlemanWunschGotoh seems to reverse the sequences when s1 is
shorter than s2. Neither of the other aligners (NW, SWG) appears to do
that. If this is an important implementation detail for the algorithm, can it
be hidden so that sequence1 and sequence2 are populated on the
alignment object with the original input index?

The goal of course is for input sequence 1 to always equal
alignment.originalSequence1().

Thank you!
