Rho: A DSL for building HTTP services with http4s

new RhoRoutes[IO] {
  GET / "hello" |>> { () => Ok("Hello, world!") }
}

The http4s-core dsl defines routes in terms of partial functions using pattern matching extractors while rho uses a set of 'rules' to match and extract information from the request.
Rho maintains meta data such as the names of extracted parameters and their types which can be reused for tasks such as generation of Swagger documentation.
Rho routing is implemented as an efficient tree structure as opposed to a linear search.
