  Usage
  $ laf <input>

  Input Options (only choose one)
  1. gen, generate -> Generate required config boilerplate   
  $ laf gen

  2. f, fetch -> Download everything specified in your config file (.laf.json)
  $ laf fetch

  Flags (can be used together)
  1. --out, -o -> Download everything to specified directory
  $ laf --out "./my/directory"

  2. --cut, -c -> Download all PNGs (ie. the "file cut") from your kit
  $ laf --cut "PNG"
