Dockerizing an application

Containers are made up of images. Images contain your project and it's dependencies.

Add a Dockerfile to the start project. The Dockerfile should do the following...
- Include a base Node image
- Copy all the project files into the image
- Run an npm install
- Expose port 3000
- Run npm start
Build the image
