/**
 
 The following is a routes file for a Vapor server that exposes two routes, "get" and "set", both of which accept query params.
 
 The "get" route returns the value of a given key if it exists, while the "set" route stores each provided key/value pair in a Redis cache.
 As per Vapor's conventions, the Redis configuration exists in the `Sources/App/Controllers/configure.swift` file which is not included in this Gist.
