[Shop Feature] Tax Collector 1.0.0

Have you thought about the possibility of creating a system of Politics? Where clan leaders can collect excise taxes on items in a particular region?
I created this system to be able to collect a rate of purchases made on NPCs.
It's a very basic system but it might be useful to someone.

PS: I tried to create a system similar to NST_MARKET, but unfortunately I did not succeed.
