USAGE

var parse = require('parse-json-response')

// Handy response-event-handler function returny thing

// parse(cb) -> function(res)
http.get(someApi, parse(function(er, data, res) {
  if (er)
    console.error('it failed', res.headers, er)
  else
    console.error('it worked', res.headers, data)
}))

// or, if you have the response object somehow already

http.get(someApi, function(res) {
  // parse(res, cb) -> null
  parse(res, function(er, data) {
    if (er)
      console.error('it failed', res.headers, er)
    else
      console.error('it worked', res.headers, data)
  })
})

If the response statusCode is not in the 2xx range, then it's assumed to be an error, and will create an error object. The error object returned is decorated with statusCode. The data arg is always set if the response body was parseable.
