Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

/affini-tech/ChartFactory

Based on D3.JS and Dimple, ChartFactory provide the ability to build quickly D3.JS charts without coding any lines of javascript. Just define your dashboard in a JSON and voila !

charts: [
        {id:'chart1',
         width:800,height:250,

xAxis:{type:'Category',field: "Month",orderRule:'Date'},
