/**
* Creates a continuation function with some arguments already applied.
*
* Useful as a shorthand when combined with other control flow functions. Any
* arguments passed to the returned function are added to the arguments
* originally passed to apply.
*
* @name apply
* @static
* @memberOf module:Utils
* @method
* @category Util
* @param {Function} function - The function you want to eventually apply all
* arguments to. Invokes with (arguments...).
* @param {...*} arguments... - Any number of arguments to automatically apply
* when the continuation is called.
* @example
*
* // using apply
* async.parallel([
* async.apply(fs.writeFile, 'testfile1', 'test1'),
* async.apply(fs.writeFile, 'testfile2', 'test2')
* ]);
*
*
* // the same process without using apply
* async.parallel([
* function(callback) {
* fs.writeFile('testfile1', 'test1', callback);
* },
* function(callback) {
* fs.writeFile('testfile2', 'test2', callback);
* }
* ]);
*
* // It's possible to pass any number of additional arguments when calling the
* // continuation:
*
* node> var fn = async.apply(sys.puts, 'one');
* node> fn('two', 'three');
* one
* two
* three
