Pathfinder-UI is a tool that allows you to visualize and test the routes in an Express application. ### Interactive Tree View 
Put our pathfinder-ui routing where you keep your middleware.
`js``
app.use('/pathfinder', function(req, res, next){
pathfinderUI(app)
next()
}, pathfinderUI.router)
pathfinderUI(app) grabs your express routes and passes the data into the pathfinder module.
You access the interface by going to localhost:PORT/pathfinder
