This PR splits the ERT file up into a bunch of files, to edit them later much easier.
1 Doctor (Lead), intended to do advanced medical stuff to heal people.
2 Paramedics, intended to bring injured to the doctor. (Can likely also do advanced medical stuff, but the doctor should be the primary one to do so)
1 Bodyguard, intended to stay with and defend in the IAC team. (Also trained in medical procedures, but not super advanced.)
