Modified pairwise to report all in one file.

+ minor improvements to output format
Removed the pairwise method (will implement as part of cross-filter).
Input files for cross-filter specified in a loki.conf, output corrected columns for all individuals.
Assess by corrected values, but report original (uncorrected).
Sort columns by input names, prepend header.
cross-filter is now called assess-dynamics

It retains all windows now, so "filter" isn't a good name anymore.
Instead of filtering out uninteresting windows,
it annotates them with "growing", "declining", "concordant", "heterogenous".
All-inclusive method "assess-dynamics"

-- in lieu of "pairwise" and "cross-filter".
