Building world-cup.json - Open (free) public domain world cup in Russia 2018 football datasets in JSON with Ruby (and the sportdb machinery)

Hello,

   using the sportdb machinery (gems, command line tools and build
scripts in ruby) I've put together a [new free public domain dataset
for the (football) world cup in Russia 2018 [1]. The world's biggest
(sport) event kicking off in about a week.

   Enjoy the beautiful game with ruby and datasets in json or sql :-).

PS: Find the [(activerecord) sql to json script [2] in the yorobot
automation repo.
