Goals

• Document what authz can and cannobe used for
• Design, implement & document a basic example that others can learn & build off of

Deliverables

• Everything necessary (.json file, Makefile target, LocalNet account, etc...) to allow an onchain account to delegate to the DAO address
• Makefile target that sends funds from "User1" to "User2" where the DAO address signs the message and User1 != DAO
• New pages in the docs that presents & explains this
