/**
 *  The '--production' parameter allows to minimize the JS and CSS code.
 *
 *  Minimal requirements: NodeJS v6.9+, gulp module installed globally, i.e., use 'npm install -g gulp'.
 *
 *  NOTE: for the first time, one need to execute: 'npm install' to get all the NodeJS
 *        dependency modules described in the package.json file and used by this gulp file.
