code: function getLeaguesIdTable(id, cb){
      footballDb
          .getLeaguesIdTable(id)
          .then(data => cb(null, data))
          .catch(err => cb(err))
  }
docs: Every action parameter (e.g. id) taking part of method's name (e.g. _id_)
  is bound to the corresponding argument of req.params (e.g. req.params.id).
  In this case this function is useless and we could simply bound
  property 'getLeaguesIdTable' to method `footballDb.getLeaguesIdTable`.
