asyncMap(values, iterator, callback) -> result

Performs iterator on each value in values in parallel, and passes the result into callback when complete.

• iterator(value, callback): Any function that receives a value and a callback, e.g. fs.stat(path, callback)
• callback(err, result): The function called upon completion or abortion of the mapping process
