Comment(by was):
This is now ready for review. Some notes:
1. Don't bother looking at the diff, except for time_series.pyx and
module_list.py. Just look at at the files in stats/hmm, which are all
new, and stats/intlist.pyx.
2. There are a number of very small API changes (for the better). This
technically violates our DeprecationPolicy. However, frankly, the current
code was -- upon inspection -- so bad, that there is no way anybody was
actually using it for anything serious. (As was evidenced by the response
on sage-devel.) And the API is only a tiny bit changed now.
3. I do have a long list of possible followup projects. However, I
wanted to make a first solid release that at least has enough to replace
the existing HMM functionality in Sage, before adding lots of new stuff.
