@yu-iskw that makes sense! I do think the linkage matrix / merge list is a
general enough data structure for this algorithm that it's definitely worth
having as an output, and doesn't actually depend on scipy. The way you had it
before is, I think, basically the same thing used in
[scipy](http://docs.scipy.org/doc/scipy/reference/generated/scipy.cluster.hierarchy.linkage.html#scipy.cluster.hierarchy.linkage),
[R](https://stat.ethz.ch/R-manual/R-patched/library/stats/html/hclust.html),
and [matlab](http://www.mathworks.com/help/stats/linkage.html). I would call
the method `toLinkageMatrix`, that seems to be the most common name.
