Rename method _hashLeaf to something that represents the validity of the leaf
The method `_hashLeaf` accepts 3 arguments.\\n```\\nfunction \\_hashLeaf(uint32 user\\_id, uint256 user\\_amount, bytes32 leaf) private returns (bool) {\\n```\\n\\nThe arguments `user_id` and `user_amount` are used to create a keccak256 hash.\\n```\\nbytes32 leaf\\_hash = keccak256(abi.encodePacked(keccak256(abi.encodePacked(user\\_id, user\\_amount))));\\n```\\n\\nThis hash is then checked if it matches the third argument.\\n```\\nreturn leaf == leaf\\_hash;\\n```\\n\\nThe result of the equality is returned by the method.\\nThe name of the method is confusing because it should say that it returns true if the leaf is considered valid.
Resolution\\nClosed because the method was removed in gitcoinco/governance#4\\nConsider renaming the method to something like `isValidLeafHash`.
```\\nfunction \\_hashLeaf(uint32 user\\_id, uint256 user\\_amount, bytes32 leaf) private returns (bool) {\\n```\\n
