[ColeMorton]

@dignifiedquire Using your snippet from: #55.

ipfs.cat('some hash', function (err, stream) {
  var res = ''

  stream.on('data', function (chunk) {
    res += chunk.toString()
  })

  stream.on('error', function (err) {
    console.error('Oh nooo', err)    
  })

  stream.on('end', function () {
    console.log('Got:', res)
  })
})

Thank you, sorry for the delayed answer. Could you please make sure that linting passes on the code, other than that it looks good :)

This will also require a rebase from master onto this branch.

@ColeMorton ping :) Can you get linting to pass and master rebased onto this branch for the merge? thank you

[daviddias]
