What Actually Is The MC Command Centre Mod?

The MCC mod is a very handy mod to have it does many things such as clearing relationships, weeding out sims, stopping annoying actions (like constant checking the phone), washing hands, autonomous flirting. Well you get the idea on those. It also can remove relationships and also set relationships between other sims as well.
Basically you'd just have to play around because telling what all the features do would just take too long.
