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'
