Proxy with Inheritance

Task 5
Implement a basic Proxy contract which has the following code in its fallback function
assembly {
    let ptr := mload(0x40)
    calldatacopy(ptr, 0, calldatasize)
    let result := delegatecall(gas, _impl, ptr, calldatasize, 0, 0)
    let size := returndatasize
    returndatacopy(ptr, 0, size)
​
    switch result
    case 0 { revert(ptr, size) }
    default { return(ptr, size) }
 }

Implement the Score contract as before and use the Proxy contract with remix 
Implement ScoreV2 and change the proxy address to point to that
