-// Amsterdump is a small program that populates a BigQuery table with
-// a matrix of origin points scattered around Amsterdam and each
-// respective points travel time to a given destination.
-//
-// The two destinations used here are the Schiphol Airport and
-// Amsterdam Central station.
-//
-// To accomplish this the Google Maps Distance Matrix API [1] is
-// queried with the points. A visualisation is later done using
-// BigQuery GeoViz[2].
