help with / merge with flipper package

[mpadge]

Just saw this repo, which seems to have similar aims to the flipper package. Development there has been stalled for a while, but I hope to get it going again soon. It'd be great if you wanted to help there - let me know. (The name refers to ultimate vision of a shiny app with swipey motion, so a phrase can start a search, and the flips/swipes intelligently navigate the package similarity matrix.)
