// Collect funds in a payable `stake()` function and track individual `balances` with a mapping:
// ( Make sure to add a `Stake(address,uint256)` event and emit)




// After some `deadline` allow anyone to call an `execute()` function

// If the deadline has passed and the threshold is met, it should call `exampleExternalContract.complete{value: address(this).balance}()`

// If the `threshold` was not met, allow everyone to call a `withdraw()` function

// Add a `withdraw()` function to let users withdraw their balance

// Add a `timeLeft()` view function that returns the time left before the deadline for the frontend

// Add the `receive()` special function that receives eth and calls stake()

//  receive() payable external {
//     stake();
// }
