// When `balanceOf(_user)` is changed (via minting/burning/transferring tokens),

// To keep the `dividendOf(_user)` unchanged, we add a correction term:
// `dividendOf(_user) = dividendPerShare * balanceOf(_user) dividendCorrectionOf(_user)`,
// where `dividendCorrectionOf(_user)` is updated whenever `balanceOf(_user)` is changed:
// `dividendCorrectionOf(_user) = dividendPerShare * (old balanceOf(_user)) - (new balanceOf(_user))`.
