Given the initial set of superimpositions, and a set of
PAIRWISE similarity scores, the TREEWISE option will
perform all alignments that are possible given a dendrgoram (generated
by considering the PAIRIWISE scores).
Statistics, transformations and alignments are output at each stage
of the hierarchy so that a continuim of structure variation can be
observed (ie. the output will get more and more structural varied
as the program progresses).
Note that by default, STAMP performs both PAIRWISE and TREEWISE procedures together.
