 * This small script simply creates an NPM package with no dependencies.  While
 * Angular CLI needs the dependencies to properly build the app, the compiled
 * product is completely self-contained.  When MAGE pulls the web app package
 * via npm install, there is no need to install all the web app dependencies,
 * only the compiled bundle that MAGE serves to the web browser.
