Extends the native readline interface with color support.

A drop-in replacement for `readline`.

Additionally accepts an options.color object with chalk colors
for `prompt` and `completer`.

@todo this could be enhanced with auto complete hints in grey.
@todo similar to this: https://github.com/aantthony/node-color-readline

@ignore

@example
const readline = require('./super-readline')

const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout,
  prompt: '> ',
  completer: readline.defaultCompleter([ 'bob', 'yolk' ]),
  colors: {
    prompt: readline.chalk.cyan,
    completer: readline.chalk.yellow
  }
})

rl.prompt()
