Mod «Dynamic Research Slots» for Hearts of Iron 4 (v1.11.1 - 1.11.13)

This mod introduces a concept of "Research Power" (RP in short), which determines how many research slots every nation in the world gets.

Requirements for unlocking each research slot:

1:  0 RP
2:  0 RP
3:  50 RP
4:  200 RP
5:  400 RP
6:  700 RP
7:  1 00 RP
8:  1 500 RP
9:  2 000 RP
10: 3 000 RP 

RP is generated by civilian & military factories, as well as naval dockyards.

I also introduced something I call "Easy Research Slots", which are slots that the nation would have otherwise (starting slots + gained through national focuses), and have their RP requirement lowered to 60%, so getting to original 5 (or 6 in some rare cases) is much easier than it would be. So be sure to not ignore those focuses that give research slot!

While certainly there is still a lot of balancing to be done, both in terms of RP requirements, as well as how much of it each building generates, I am satisfied with the current version of this mod so I decided to share it already.
