Faction functionality in the VE Framework is mostly handled through a Def Mod Extension:

• Contraband system, a system that allows you to specify a list of objects that will provoke a faction reaction when sold / gifted
• Faction Def Mod Extension, def extension that handles all the faction functionality

How do I use this code?

Explained inside the link above.

Inside the framework, the namespace to access all the Cuisine classes is "VEF.Factions"
