/*
 * Grunt.js is a task runner for JavaScript development.
 * Grunt and its plugins are installed and managed via npm, the Node.js package manager.
 * http://gruntjs.com/
 *
 * To use it:
 * 1) install node.js - http://nodejs.org/#download. This will install 'npm' (Node Package Manager) too.
 * 3) run: npm install (This will use package.json and install grunt and all dependencies)
 * 4.1) grunt jshint - checks all JavaScript files with JSHint
 * 4.2) grunt jshint:core - checks only the files in wicket-core
 * 4.3) grunt - starts the registered tasks: starting a web server and running all tests (Ajax, non-Ajax and AMD)
