 * @title SmartAccount - EIP-4337 compatible smart contract wallet.
 * @dev This contract is the base for the Smart Account functionality.
 *         - It is modular by nature. UserOp and txns validation happens in Authorization Modules.
 *         - It provides the functionality to execute AA (EIP-4337) userOps. Gnosis style txns removed to a module.
 *         - It allows to receive and manage assets.
 *         - It is responsible for managing the modules and fallbacks.
 *         - The Smart Account can be extended with modules, such as Social Recovery, Session Key and others.
