one report for each session, instead of one report for all sessions in a run,
each report should have a session summary including time it took to run (from #150),
with a file naming scheme such as index.html for the matrix and session_N.html (or derived from whatever the identifier of the session is) in the same directory.
It could have a separate, shared CSS file, too, instead of inlining.
We want:
index.html
for the matrix andsession_N.html
(or derived from whatever the identifier of the session is) in the same directory.
