Looks like tutorial code/docs are outdated again.

I'm going through the tutorial and a few things wouldn't work as described. First the Makefile, One of the lines in the make file is this @cat ./node_modules/radar_client/node_modules/engine.io-client/dist/engine.io.js >> public/radar_client.js But it throughs an error saying the directory could not be found. sure enough, there is no engine.io-client in the radar_client/dist/ folder. I changed the line to use the engine.io module that I had to download. this got me through the Makefile but when I try to run the Radarclient.alloc() function it never connects to the server. it returns a 404 error at the following url path /engine.io/?EIO=3&transport=polling&t=N1LIQMB and then returns this error

radar_client socket closed null transport error Error: xhr poll error
    at XHR.Transport.onError (radar_client.js:1751)
    at Request.<anonymous> (radar_client.js:1140)
    at Request.Emitter.emit (radar_client.js:3164)
    at Request.onError (radar_client.js:1322)
    at radar_client.js:1269

Im not sure how to fix this one.
