Document how merging states works

[wvpm]

Problem

In Victoria 2 a state can be split between countries. An example of this is Osthannover being split between Bremen, Hamburg and Hannover. All three countries can build factories and a port in their part of the state. When the state is united, there may only be 1 port and max 8 factories. How does Victoria 2 decide which port and which factories to keep?

OpenVic needs to faithfully recreate this behaviour. The inner workings are currently unknown and need to be discovered and documented.

Solution

Experiment with uniting states in Victoria 2 to figure out the following:

• Does building level matter?
• What happens to duplicate factories?
• Does it matter whether a factory is closed or open?
• Does the subsidies checkbox keep its value?

If you find other things that play a role here, document them as well. When using other people's findings, from project alice, reddit or paradox forums for example, always verify their claims in Victoria 2.

Document your findings in OpenVic/docs/simulation/.

Did a bit of testing, I'll make a PR with the docs in a minute.
