emacs: set company-idle-delay to 0.2 seconds
emacs: add git-timemachine

no keybinding for it - although it seems useful I doubt I'll use it
often enough that M-x git-timemachine will be too time consuming.
emacs: add anaconda-mode

and company-anaconda. provides jump to definition, eldoc, and
auto-complete (and maybe more) for python.
