gnostic-condition branch on OwlWilderness/se-2 repository

This is the working repository for code in this demo.

https://github.com/OwlWilderness/se-2/tree/gnostic-condition

The import format was modified to use @Openzepplin instead of a github reference in all files.

SafeMath was included for uint in the Conditional Tokens contract.

contract ConditionalTokens is ERC1155 {

    using SafeMath for uint;

...

String Utilities were added to the CT Helper Contract to support a method to return the position ID as a string

**the scaffold eth debug contract getPositionId(…) returns the uint as floating point eth

example:

function getStringPositionId(IERC20 collateralToken, bytes32 collectionId) internal pure returns (string memory) {
         return Strings.toString(uint(keccak256(abi.encodePacked(collateralToken, collectionId))));
}

The Gist repository provides one contract to execute and mint multiple collateral tokens using different name and symbol.

Two contracts are created and deployed in scaffold-eth as the deployed contract object uses the name of the contract as the key.

**without doing this OOB the debug contract page will only show for one of the collateral tokens
