Subject: [PATCH] gameStore: Added functions to add and retrieve games

Implemented the createGame function which creates a new game, generates
it's id and adds it the the games map.

Also added the retrieveGame function which retrieves a game, given it's
id.

Also added the uuid package to generate unique ids for games.

Fixes #5
