// EXERCISE: Refactor the game store to funcs - step #3
//
//  Let's continue from the previous exercise. This time,
//  you're going to add json encoding and decoding using
//  funcs.
//
//  1- Create a new command in a func that encodes the
//     game store data to json and terminates the program.
//     Lastly, add it to runCmd func.
//
//     For more information, see: "Encode" exercise from
//     the structs section.
//
//        Name  : cmdSave
//        Inputs: []game
//        Output: bool
//
//  2- Refactor the load() to load the games from the
//     `data` constant (it's in the games.go as well).
//
//     For more information, see: "Decode" exercise from
//     the structs section.

  > list   : lists all the games
  > id N   : queries a game by id
  > quit   : quits
