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');

Those suck for maintenance and they're ugly.

Possible solutions

/* Define two variables as the loop limits */
@from : 0;
@to : 10;

/* Create a Parametric mixin and add a guard operation */
.loop(@index) when(@index =< @to) {

  /* As the mixin is called CSS is outputted */
  div:nth-child(@{index}) {
    top: unit(@index * 100, px);
