**Author:** Daniel Yamagata

A base contract for governor that defines upgradeability logic and modifiers for access control

*All governors are able to execute arbitrary transactions. Therefore, they are able to call the Mezz Migrator to upgrade themselves to a newer version. Specifically, the governor should call the Mezz Migrator's upgradeToNewerVersion() However, resetting to a patched version may not be possible depending on the protocol state. Therefore, a function to execute this callback is provided via 'Patchable'*
