/*
 * This file shows exporting as specified by CommonJS, the version traditionally used in Node.js, but not the way indiciated in the ECMASCRIPT specification.
 * Exporting allows constructs in one file to be made available in another.
 * Any kind of value can be exported: numbers, strings, arrays, functions, objects, etc
 *
