Initial Review

[ryjones-dev]

This PR compares the current state of the repo as of 10PM 12/18/21 and compares it to an empty branch with no code, so that I am able to easily make comments for a repo review. Do NOT merge this PR.

Some general comments that I saw in multiple places:

• A lot of the review is "why is this code here?". Code responsibility is a concept that takes a lot of practice to master.
• There's an overuse of public, and not just in MonoBehaviours. Unity's components often get a pass for having a lot of public variables, because that's how a lot of resources online use public to have it show up in the inspector. But you can also use [SerializeField] private to accomplish that, while maintaining privacy. In general, default to private and then use public properties if you need read-only access in other classes. If you are trying to modify data from outside the class, you're probably doing something wrong.
• It looks like there's a lot of common network code both in ClientRef and GameServer. Because of that, it's hard to follow who is responsible for what code. Consider grouping client and server code into their own namespaces so it's not so easy to cross that line.
• Don't use GetComponent() more than absolutely necessary. It's an expensive operation. Avoid calling it per frame or in a loop, and cache any calls you make for reuse.

I see you have a mix of variables prefixed with underscores and others without, which throws me off as a reader. A common C# coding convention is to use an underscore to denote a private member variable. I would either forego the underscores or only use them on private member variables.

I would always add an access modifier to every variable for consistency and readability.
