/**
 * Adds shared state to a component.
 *
 * The purpose of shared state is to store framework component state at significant container
 * boundaries in order to restore it when the "same" component is mounted later.
 *
 * "Sameness" is determined by the `idProp` config member (defaults to "id"). If multiple
 * descendants have the same `idProp` within the subtree, SharedStateDecorator will not distinguish
 * between them and will allow each to read from and write over each other's data.
 *
 * For example, Panels and Panel are considered "significant container boundaries" since they are
 * key building blocks for applications. When components are rendered within a Panel, we may want to
 * store those components state on unmount so that we can restore it when returning to the panel.
 * Panel can (and does) use SharedStateDecorator to establish a shared state which can be used by
 * contained components.
 *
 * It's important to note that SharedStateDecorator doesn't prescribe how or what is stored nor how
 * the data is managed. That is left to the consuming component to determine. Also, unlike React
 * state or third-party state management solutions like Redux, updating shared state will not
 * initiate an update cycle in React. The intent is only to restore state on mount.
 *
 * If shared state is used in the render method for a component, it may be necessary to use the
 * `updateOnMount` config member which will initiate an update cycle within React once the data is
 * available from an upstream shared state.
