NPCC v.1.1.6 (Patreon)

 Added in-game menu(on sim) with following options:
1) AssignNPCJob
2) RemoveNPCJob
3) AssignNative
4) RemoveNative

Please, read my notes first:
AssignNPCJob - please be aware that to achieve correct assignment for lot-bound jobs like librarian, bartender etc., you must use this option on that lot. For example you want sim named Marcus Flex to be a Gym Trainer. Travel with Marcus to gym lot, one that you want Marcus to work at(or for example you can summon Marcus to that lot with MCCC). Click on Marcus - More Options - NPCC - AssignNPCJob - GymTrainer. Find current gym trainer on lot, Click on him - More Options - NPCC - RemoveNPCJob. Travel to another lot and go back on gym lot. Now you should see Marcus working as Gym Trainer.  You can see steps for this example on new screenshots attached to this post.
AssignNative - this option allows you to assign sims as Selvadorada Natives. Please use only homeless sims for that!
