Error for fully public contract.

[lydiagarms]

When a contract is fully public and no secret variables are used in any of the functions, we should get a zappify error as there is no need to use starlight, for example:

pragma solidity ^0.8.0;

contract Receipt {

mapping (address => Rct) private total;
secret uint256 a;

struct Rct {
uint256 amount;
uint256 tax;
}

function add(Rct memory myrct, address user) public {
total[user].amount += myrct.amount;
total[user].tax += myrct.tax;
}

}
