need to create Document index too
load document plugin
got basic title metadata extraction working
improved document metadata extraction which now replaces previous getHref jschannel rpc call
removed elife and peerj hack
added latest document and store plugins from okfn annotator/master
removed diff marker from previous merge
use latest annotator-store from hypothesis dev
[bootstrap] only prompt in interactive shells
use user-wide pip cache by default
