@zmorrell, I am done cleaning this up and it is ready for you to have a look before we merge it. There are a lot of revisions in the algorithm section, the changelog has a summary of them.

[zmorrell]

Pretty much everything looks good to me. There is only one potential bug I found, and everything else is to make the code cleaner

[ccoffrin]

great suggestions. Thanks!
