Method returns bool but result is never used in TokenDistributor.claimTokens
The method `_delegateTokens` is called when a user claims their tokens to automatically delegate the claimed tokens to their own address or to a different one.\\n```\\n\\_delegateTokens(user\\_address, delegate\\_address);\\n```\\n\\nThe method accepts the addresses of the delegator and the delegate and returns a boolean.\\n```\\n/\\*\\*\\n\\* @notice execute call on token contract to delegate tokens \\n\\* @return boolean true on success \\n\\*/\\nfunction \\_delegateTokens(address delegator, address delegatee) private returns (bool) {\\n     GTCErc20  GTCToken = GTCErc20(token);\\n     GTCToken.delegateOnDist(delegator, delegatee);\\n     return true; \\n} \\n```\\n\\nBut this boolean is never used.
Remove the returned boolean because it's always returned as `true` anyway and the transaction will be a bit cheaper.
```\\n\\_delegateTokens(user\\_address, delegate\\_address);\\n```\\n
