fluent async: functional programming support for asynchronous functions.

fa = fluent/functional async

fa is a fluent and functional async library. Inspired by async[1], it takes the functional operators, and adds some modifiers, to enable a queue depth, run to completion regardless of errors, run in series, and add an index to the callback.

  function(num,cb) { cb(null, num*2); },
  function(errresult) { console.log(result); }
