Old behaviour:
==============
creativity-series previously removed non-finite values, and sorted the
rest, producing something like:
t,1st,2nd,3rd,...
2,10,11,12
3,3
(where t=0 and t=1 have no finite values, t=3 has only one non-finite,
etc.). This discards any association with the files they come from,
however, which means any sort of source-based confidence exclusion is
impossible.
creativity-series-quantiles then used these pre-sorted values to produce
another .csv of quantile values.
createivity-series-graphs accepted either one--if the series file, it
calculated quantiles on the fly; if the quantiles, it used the
pre-calculated quantiles.
New behaviour:
==============
creativity-series now just generates something like:
t,source1,source2,source3
0,nan,nan,nan
1,nan,nan,nan
1,12,10,11
2,nan,3,nan
which creativity-series-quantiles and creativity-series-graphs now
understand: they does the nan trimming and sorting, then calculate
quantiles.
creativity-series-graphs also gains an entirely new ability, with flag
--source-confidence (but only when given a creativity-series file): to
select a confidence region by excluding (1-x)% of source files, then
plotting the minimum and maximum values remaining after removal of the
most non-median values. This is done by calculating (p-0.5)^2 for the
inverse quantile p for each time period, then summing these up across
time periods: the source files with the largest scores are excluded.
(see --help for the gory details).
