I need to be able to run tests so I can make PRs for this project.
So this will be my first PR I think.

As you can see, basic stuff is running now on PowerShell but I don't have MongoDB installed.
Also, I am not sure whether my changes aren't breaking stuff on Unix/Mac.
So I think I will need some help from you to complete this.

For Mongo, we might consider starting a Mongo server with Docker? At my work we are doing this and the nice thing about it is that you can just check out a project and it has a docker-compose.yml file that pulls, installs and starts a Docker image with the database in it and you are all set up.

I'd be willing to try that here but have to know what you think about all this first.
Let me make a PR so you can have a look at what I'm doing and see if you agree.

Notice that I'm executing Bash scripts like bin/check-deps by prepending bash to the command:

bash bin/check-deps

The 'shebang' in the first line of the file has no effect on Windows.... But bash works as long as you either have Git for Windows or Windows Subsystem for Linux (WSL) installed. Not sure which because I have both... But I wonder whether this breaks on Unix/Mac? If not it's a good solution I think. Let me know your thoughts.
