 A *grant* is an allowance to execute a Msg by the grantee on behalf of the granter.
 Authorization is an interface that must be implemented by a concrete authorization logic to validate and execute grants. Authorizations are extensible and can be defined for any Msg service method even outside of the module where the Msg method is defined. See the `SendAuthorization` example in the next section for more details.
