Matrix

Given a string representing a matrix of numbers, return the rows and columns of that matrix.

So given a string with embedded newlines like:

9 8 7
5 3 2
6 6 7

representing this matrix:

    1  2  3
  |---------
1 | 9  8  7
2 | 5  3  2
3 | 6  6  7

your code should be able to spit out:

A list of the rows, reading each row left-to-right while moving top-to-bottom across the rows,
A list of the columns, reading each column top-to-bottom while moving from left-to-right.

The rows for our example matrix:

And its columns:

Setup

Go through the setup instructions for Javascript to install the necessary dependencies:

Install assignment dependencies:

$ npm install

Execute the tests with:

$ npm test

In the test suites all tests but the first have been skipped.

Once you get a test passing, you can enable the next one by changing xtest to test.
