[AlphaSerpentis]

File(s): Every Smart Contract That Aren't Interfaces in contracts/mimic
Test Files Required?: Yes
What Testing Should Include:

• Ensure only "admin" (aka governance) can perform onlyAdmin functions.
• Ensure the "admin" can be transferred.

Project Mimic should be able to support governance in the future as time progresses. It's part of the idea of Project Mimic being a community project.
