Examples
Sample code invoking the runAsync function

Run a function asynchronously and get the result

future = runAsync(function(){
	return "Hello World!";
});
writeOutput(future.get());

Expected Result: Hello World!

Run a function after the asynchronous function and use a five milliseconds timeout when calling get()

future = runAsync(function(){
	return 5;
}).then(function(input){
	return input + 2;
});
result = future.get(3); // 3 is timeout(in ms)
writeOutput(result);

Expected Result: 5

Run a function asynchronously with then() and error()

future = runAsync(function(){
	return 5;
}).then(function(input){
	return input + 2;
}).error(function(){
	return "Error occurred.";
});
writeOutput(future.get());

Expected Result: 7
