/*
 * The function flattens an arbitrarily nested array of k-dimensions using recursion.
 * The implementation is quite fast (i.e. O(n) where n is the total number of 
 * elements in the k-th dimensional array where k >= 1).
 * However stack overflow errors could occur in cases where k is particularly large - 
 * thus requiring a very deep level of recursion. 
 *
 * @param {number[][]} - A k-dimensional array where k >= 1
 * @returns {number[]} - A 1-dimensional flattened array
