The following is my first real attempt at batch scripting. I'm new to it, so I'm not sure if I want to apply best practice. The code works and I am open to suggestions.

Basically, the following code allows you to download Node.js and npm per project. This is a requirement for us to be able to run multiple versions of Node and npm simultaneously. The script also means that setting up development environments is easier. So there are some goals this script should achieve.
