/**
 * The "consumer level" part of Decoration
 *
 * `ClasslistComposite` contains composited classnames from all the decorations applicable to a target
 *
 * The composite includes all the applicable inheritances and negations.
 *
 * Note that due to performance considerations, `ClasslistComposite` is one of the few cases where
 * we *do not* use `Disposables` for event management and instead use old school `addChangeListener`/`removeChangeListener` methods.
 *
 * Remember to pass same **named** function reference to `addChangeListener` and `removeChangeLiseneer` while subscribing and unsusbscribing
 * in `componentDidMount` and `componentWillUnmount` respectively.
 *
 * Note: You should also implement a `componentDidUpdate` hook where you can unsubscribe from previous decoration object and subscribe to the new one.
