 Pairtree infers the phylogeny underlying a cancer using genomic mutation data.
 Pairtree is particularly suited to settings with multiple tissue samples from
 each cancer, providing separate estimates of subclone frequency from each sample

 1. Compute pairwise relation tensor over all mutations (or clusters of
    mutations). This provides the probability over each of four possible
