/* the above deserves explanation:
* - accscore_o is the accuracy of the originally emitted trace, according
* to the generic posterior decoding matrix <gx2>. This is a lower bound
* on the expected # of accurately aligned residues found by a DP
* optimization.
* - accscore is the accuracy found by the fast (vector) code DP implementation.
* - accscore_g is the accuracy found by the generic DP implementation.
* accscore and accscore_g should be nearly identical,
* within tolerance of roundoff error accumulation and
* the imprecision of Logsum() tables.
* - accscore_g2 is the accuracy of the traceback identified by the generic
* DP implementation. It should be identical (within order-of-evaluation
* roundoff error) to accscore_g.
*
* the "accscore_g2 < accscore_o" test is carefully contrived.
* accscore_o is a theoretical lower bound but because of fp error,
* accscore and (much more rarely) even accscore_g can exceed accscore_o.
* accscore_g2, however, is calculated with identical order of evaluation
* as accscore_o if the optimal trace does turn out to be identical to
* the originally emitted trace. It should be extremely unlikely (though
* not impossible) for accscore_o to exceed accscore_g2. (The DP algorithm
* would have to identify a trace that was different than the original trace,
* which the DP algorithm, by order-of-evaluation, assigned higher accuracy,
* but order-of-evaluation in traceback dependent code assigned lower accuracy.
