// ARTIFACT ///////////////////////////////////////////////////////

// added as part of the ingress #13magnus in november 2013, artifacts
// are additional game elements overlayed on the intel map
// currently there are only jarvis-related entities
// - shards: move between portals (along links) each hour. more than one can be at a portal
// - targets: specific portals - one per team
// the artifact data includes details for the specific portals, so can be useful
