 * @title DharmaUpgradeMultisig
 * @author 0age (derived from Christian Lundkvist's Simple Multisig)
 * @notice This contract is a multisig that will control upgrades to the Dharma
 * Smart Wallet and the Dharma Key Ring via the Dharma Upgrade Beacon Controller
 * Manager. it is based on Christian Lundkvist's Simple Multisig (found at
 * https://github.com/christianlundkvist/simple-multisig). The address of the
 * Dharma Upgrade Beacon Controller Manager is hard-coded as the only allowable
 * call destination, and any changes in ownership or signature threshold will
 * require deploying a new multisig and transferring ownership of the upgrade
 * beacon controller manager.
