the first pie chart uses no classification.  if we had to classify, we
would have stubs only end as paths (_foo$) and transits are all the

i do not know how we would separate small and large transits in any
rigorous fashion.  so it was easier to use the ucla taxa as a rough
approximation and blame anything weird on them :)

we could do a quick run using the definition of stub and transit as
above if folk are really interested.
