/*
    The following code illustrates the use of the Bing Distance Matrix package
    for calculating a distance matrix with one or more origins and one or more
    destinations. The 'getDistanceMatrix' method fetches the distance and
    travel time for every origin-destination combination possible for the
    chosen mode of travel.
