Add docs that explain how to migrate an express app to huncwot #83
Description
Context
It'd be helpful to describe possible migrations paths.
One idea:
const express = require('express')
const Huncwot = require('huncwot')
const app1 = express()
const app2 = new Huncwot()
app1.get('/', () => /* proxy to app2 here */)
app2.get('/', () => 'foo')
app1.listen(3333)
app2.listen(3334)Not ideal for performance for sure, but it should make it easier to migrate apps step by step
