/**
* Calls `callback` on a later loop around the event loop. In Node.js this just
* calls `process.nextTick`. In the browser it will use `setImmediate` if
* available, otherwise `setTimeout(callback, 0)`, which means other higher
* priority events may precede the execution of `callback`.
*
* This is used internally for browser-compatibility purposes.

* @param {Function} callback - The function to call on a later loop around
* the event loop. Invoked with (args...).
* @param {...*} args... - any number of additional arguments to pass to the
* callback on the next tick.
* @example
*
* var call_order = [];
* async.nextTick(function() {
* call_order.push('two');
* // call_order now equals ['one','two']
* });
* call_order.push('one');
*
* async.setImmediate(function (a, b, c) {
* // a, b, and c equal 1, 2, and 3
* }, 1, 2, 3);
