 *   node.js script which has 8 location variables including name, lat, lon, and elevation.
 *   loops over the locations sending them to open-meteo requesting temperature min and max for 7 days, no hourly.
 *   uses units for USA such as fahrenheit, inches, mph.
 *   prints the location name and elevation with the average high and low for the week.
