Wrong constants for time delay
This protocol uses several constants for time dealy and some of them are incorrect.\\nIn `isoUSDToken.sol`, `ISOUSD_TIME_DELAY` should be `3 days` instead of 3 seconds.\\n```\\n    uint256 constant ISOUSD_TIME_DELAY = 3; // days;\\n```\\n\\nIn `CollateralBook.sol`, `CHANGE_COLLATERAL_DELAY` should be `2 days` instead of 200 seconds.\\n```\\n    uint256 public constant CHANGE_COLLATERAL_DELAY = 200; //2 days\\n```\\n
2 constants should be modified as mentioned above.
Admin settings would be updated within a short period of delay so that users wouldn't react properly.
```\\n    uint256 constant ISOUSD_TIME_DELAY = 3; // days;\\n```\\n
