Add hospitals to the game

Make a hospital building and when troops are in the city then at day change your troops will regain more health than they normally would.

some other ideas

-In major cities have a 'hospital' which are the most effective but also expensive

-in rural cities have a 'field hospital' which is less effective but not as expensive as hospitals but still expensive

-you can level up hospitals and make them more effective

-maybe only able to be built in core provinces

-maybe only able to be built in major cites

-maybe remove the auto heal at day change to help balance out hospitals being added

-troops wont heal at day change if an enemy troop is in the city or if troops are fighting in the city

I think hospitals would helpful but they would also have to be expensive to help balance them, I also think taking out the current system that regains 15% of troop health at day change might help balance them out
