    <p>Using <code>callbacks.empty()</code> to empty a list of callbacks:</p>
    <pre>
// 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
