hw_w01-d01-submission Complete first git push and pull

There was a lot to get our heads around today. Hopefully I'll remember to mention everything we went over:

1. Basic Ruby commands
2. Getting acquainted with the Terminal
3.  REPL and irb
5. A lot of Git and GitHub stuff.

The first of the 2 commits below is Jack's example of how to use string interpolation. The second commit is me playing around with some of the ruby concepts we learnt in the first half of the day.
