Apparenly a packed scene can't reference another
packed scene, or else you get circular dependencies.

So the main scenes will send up enums instead
of the scenes directly to request scene transitions.

I've created the framwork for a review screen.

I also want to decouple the scenes from each other as best I can.

So, I'm working on creating a data mock that will let me test in isolation
using resources.

Better system for loading levels, also we have a day in review now that prints out the learned daily data

Fixed settings breaking the lobby setup. Also, we can now configure the cards the stock controller gets

- Refactored player buy / sell structure & signals
- Players can buy / sell while other player controls

Moved a lot of folders and files around to organize the space.

Now, we only accept input for buy / sell before we reveal the stock
difference.

We also show hour glass and check marks for players who haven't and ahve
bought stocks respectively.

Next step is to skip the timer once everyone has bought.

- Remade the delta object so that it doesn't throw errors.
- Now we have a reset animation to reset the deltas.
- Deltas now end the hour with a signal call
  - Calls up to Stocks Parent
  - Calls to next object to reset
- Deltas now get centerex
