use vagrant to reproduce the environment for development/testing

When trying the readme i got an error

module.js:340
    throw err;
          ^
Error: Cannot find module 'buffermaker'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)
    at Module.require (module.js:364:17)
    at require (module.js:380:17)
    at Object.<anonymous> (/vagrant/lib/KafkaConnector.js:2:19)

    at Function.Module._load (module.js:312:12)

so I reproduced it on the VM, maybe something else has to be done with another include or package or something?
