solidity合约里面定义的合约是如何定义的，有点理解不清楚 

pragma solidity ^0.4.22;

contract father{
    
    function dahan() external pure  returns(string){
        
        return "dahan";
    }
    
}
contract outside{
    
    father public f= new father();
    function testf() public view returns(string){
        return f.dahan();
    }
}

我想问一下，这个 outside 合约里 new 了一个 father 合约，它是不是算 outside 合约的成员变量？如果它和 father 是一模一样的，那它是怎么部署的？
