An external function is callable from outside the contract.
There are three types of external functions:
private: executed client-side and preserve privacy
public: executed by the sequencer and do not preserve privacy (like on the EVM)
utility: helpers that are never executed on-chain, typically used for state queries
external functions are the Aztec equivalent of a Solidity external function, though their behavior differs
slightly for public, private and utiliy functions.
external functions can also be made initializer (for contract intialization), view (for read-only behavior),
authorize_once (for basic access control) and only_self (to prevent other contracts from calling them).
