Inconsistent terminology between rewards and interest

// Uses "rewards" terminology
function fundRewards(uint256 amount) external onlyOwner {
    // ...
}
event RewardsFunded(address indexed funder, uint256 amount);

// But uses "interest" terminology
struct Position {
    uint256 tokensInterest;   // Should be tokensReward
    uint256 percentInterest;  // Should be percentReward
}

function calculateInterest(uint basisPoints, uint tokenAmount) private pure {
    // Should be calculateReward
}
