Contents of the file:

    - The "wrapper" function
    - Project and task configuration
    - Loading Grunt plugins and tasks
    - Custom tasks



Structure of the file:


  This file contains a single function which takes the 
  grunt task runner as an argument:


    function(grunt) {

        grunt.initConfig(aHugeConfigurationObjectForTheTasks);
        // When a task is run, Grunt looks for its configuration 
        // under a property of the same name.


        // load tasks from published grunt modules, 
        // for example the task 'grunt-contrib-clean' 
        // which cleans up directories
    
        grunt.loadNpmTasks('grunt-contrib-clean');
        ... load more modules



        // define custom tasks.
        grunt.registerMultiTask('js','Builds bundle for JavaScript component LW.js', function(){
          ...
        };
    
        ... more custom tasks



        // define tasks as a sequence of other tasks
        grunt.registerTask('build', ['clean:build','js']);
        ...

    }

Tasks run in the order specified. Arguments may be passed to tasks that accept
them by using colons, like "lint:files". Tasks marked with * are "multi tasks"
and will iterate over all sub-targets if no argument is specified.

The list of available tasks may change based on tasks directories or grunt
plugins specified in the Gruntfile or via command-line options.
