generate contract interfaces

[richard-ramos]

It would be interesting if flattener could be used to generate the interface of a contract, just like in this example

 1 pragma solidity ^0.5.0;
 2 
 3 contract SimpleStorage {
 4   uint public storedData;
 5 
 6   constructor(uint initialValue) public {
 7     storedData = initialValue;
 8   }
 9 
10   function set(uint x) public {
11     storedData = x;
12   }
13 
14   function get() public view returns (uint retVal) {
15     return storedData;
16   }
17 
18 }

generated interface:

  1 pragma solidity ^0.5.0;
  2 
  3 interface SimpleStorage {
  4   uint public storedData;
  5   constructor(uint initialValue) public;
  6   function set(uint x) public;
  7   function get() public view returns (uint retVal);
  8 }

(Could be part of the scaffolding instead of the flattener)
