code: function getPseudoUUID() {
    var chars = 'abcdefghijklmnopqrstuvwxyz0123456789';
    var len = chars.length;
    var ret = [];
  
    for (var i = 0; i < 10; i++) {
      ret.push(chars[Math.floor(Math.random() * len)]);
    }
    return ret.join('');
  }
docs: Not a real UUID as there's an RFC for that (needed for proper distributed computing). But in this fairly parochial situation, we just need to be fairly sure to avoid repeats.
