title: get contract creator's address in a different separate smart contract
body: <p>I want to create a dApp where one can do certain things related to a contract they've deployed. let's say it'll be used to manage a token listing site.</p>
  
  <p>I need to figure out how to verify that the address that's calling the functions matches the address that created a particular contract.</p>
  
  <p>eg. 0x01 is the contract creator of Contract A</p>
  
  <p>0x01 calls a function along with the parameter of Contract A's contract address in Contract B </p>
  
  <p>A function within Contract B then finds the contract creator's address of Contract A somehow and matches that against 0x01</p>
  
  <p>Is this possible to do in solidity?</p>
