Turns asynchronous function into synchronous

var flow = require('control-flow')
var fs   = require('fs')

flow.sync(fs, 'readFile')

flow.fiber(function(){
  var data = yield(fs.readFile(__filename, 'utf8'))
  console.log(data)

  try {
    data = yield(fs.readFile('invalid', 'utf8'))
  } catch (err) {
    console.log(err)
  }

  fs.readFile(__filename, 'utf8', function(err, data){
    console.log(data)
  })
})
