Put a closure on it

Sometimes you'll have objects that manage state along with event handling. This happens frequently in MVC apps. Let's start with a messy example:

var Launcher = function(rocket) {
  this.rocket = rocket
}

Launcher.prototype.isReady = function() {

IN_FILE="$1"
OUT_FILE="$4"

CROP_W=$2
CROP_H=$3

SIZE=$(identify $IN_FILE | awk '{print $3}')
IMAGE_W=${SIZE%%x*}
IMAGE_H=${SIZE##*x}

// data comes from here http://stat-computing.org/dataexpo/2009/the-data.html
// download 1994.csv.bz2 and unpack by running: cat 1994.csv.bz2 | bzip2 -d > 1994.csv
// 1994.csv should be ~5.2 million lines and 500MB
// importing all rows into leveldb took ~50 seconds on my machine

// there are two main techniques at work here:
// 1: never create JS objects, leave the data as binary the entire time (binary-split does this)
// 2: group lines into 16 MB batches, to take advantage of leveldbs batch API (byte-stream does this)

var level = require('level')
