// Pretty URL redirects

// These are two pieces of middleware that handle ensuring that
// URLs get formatted correctly.
// Slashes ensures that we get trailing slashes
// Uncapitalise changes case to lowercase
// @TODO optimise this to reduce the number of redirects required to get to a pretty URL
// @TODO move this to being used by routers?
