First pull request ever

Not sure of proper pull request etiquette (or if it's even appropriate in this case). 

Your strong-cluster-connect-store module was working quite nicely for me up until I upgraded to Express 4.x, which no longer depends on Connect. As such, a bunch of middleware no longer comes bundled with Express. As best as I can tell so far, that's all been fixed with my forked version (strong-cluster-express-store), which I am presenting to you now, because I figure it belongs alongside all its sibling module.
