Add consistent & meaningful comments to functions & classes.

[syntaxseed]

Much of the original library this was based on had no comments. Need helpful comments for functions, etc.

Use jsdoc style comments.

I can help with some of this.

[daltlc]

I will contribute to this as well.

I'd be happy to help as well. Since there's 3 of us should we split up some modules so we aren't overlapping on these?

[syntaxseed]

Thanks guys!

@daltlc @zargold How would you like to coordinate on this?

[zargold]

I made a PR so far: if any of you want to continue from there. That's fine or if preferred I can continue to work on it.
