Unit Repair Functionality

[sumrex]

Is it possible with the current system to have a system where units can repair other units? I have been trying to find a way but I am not an experienced C++ user so my options are pretty limited.

If there isn't a way, it would be nice if it was added because I can only assume it is a common need.

I've created an order which represents repair. periodically refills the health.
Won't push that until the repository was changed into something maintainable
