/// A trait indicating that an entity class has a comment property
///
/// This trait provides access and setting functionality for the comment
/// information of domain objects.
///
/// # Example
///
/// ```rust
/// use qubit_mixin::WithComment;
///
/// struct Task {
/// title: String,
/// comment: String,
/// }
///
/// impl WithComment for Task {
/// fn comment(&self) -> &str {
/// &self.comment
/// }
///
/// fn set_comment(&mut self, comment: &str) {
/// self.comment = comment.to_string();
/// }
/// }
///
/// let mut task = Task {
/// title: "Review PR".to_string(),
/// comment: "Check the code quality".to_string(),
/// };
/// assert_eq!(task.comment(), "Check the code quality");
///
/// task.set_comment("Focus on error handling");
/// assert_eq!(task.comment(), "Focus on error handling");
/// ```
