#### Example: Use callbacks.empty() to empty a list of callbacks:

    // A sample logging function to be added to a callbacks list
    var foo = function( value1, value2 ) {
      console.log( "foo: " + value1 + "," + value2 );
    };

    // Another function to also be added to the list
    var bar = function( value1, value2 ) {
      console.log( "bar: " + value1 + "," + value2 );
    };

    var callbacks = $.Callbacks();

    // Add the two functions
    callbacks.add( foo );
    callbacks.add( bar );

    // Empty the callbacks list
    callbacks.empty();

    // Check to ensure all callbacks have been removed
    console.log( callbacks.has( foo ) );
    // false
    console.log( callbacks.has( bar ) );
    // false
