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.

	* Solves the n-Queen puzzle in O(n!)
	* Let p[r] be the column of the queen on the rth row (must be exactly 1 queen per row)
	* There also must be exactly 1 queen per column and hence p must be a permuation of (0 until n)
	* There must be n distinct (col + diag) and n distinct (col - diag) for each queen (else bishop attacks)
	* @return returns a Iterator of solutions
	* Each solution is an array p of length n such that p[i] is the column of the queen on the ith row
