DevCongress coding exercise

Write a program that will move the heading of a table to the left side so that given the table:

a	b	c	d
[]	A	O	X

it returns

a	[]
b	A
c	O
d	X

Bonus points for proper design and use of data structures. By data structures I don't mean the stuff you find in books but merely classes, etc that make the code easy to read and understand.

Setup

Requirements

Install assignment dependencies:

$ yarn install

Making the test suite pass

Execute the tests with:

$ yarn 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 xit to it.
