Promisify.libx.js

Create promises as an object to manually wrapper for non-promisified functions.

While util.promisify is useful to convert callback-based functions to promisibable functions, promisify.libx.js is useful to manually manage resolve and reject operations.

Instead:

const stat = util.promisify(fs.stat);

stat('.').then((stats) => {
  // Do something with `stats`
}).catch((error) => {
  // Handle the error.
});

Do:

const Promisify = require('promisify.libx.js');
const p = Promisify.new();

fs.stat('.').then(stats=>{
  p.resolve(stats);
}).catch(error => {
  p.reject(error);
});

const stat = await p;

This approach allows easier to turn deep callback-based functions, spagetti or legacy code, into more modern promisiable code with fewer changes.
