/**
 * Creates a set of IdLoadAction, IdSuccessAction, and IdFailureAction. Selectors and reducers are always bundled into
 * the same structure.
 *
 * The difference between IdLoadAction and LoadAction is that IdLoadAction is parameterized by an id field. So you can
 * display loading states for multiple items that are all loading in parallel. Typical use case is you have a list of items,
 * and you can issue load actions for each one, parameterized by an id of your own choosing, and observe the loading state
 * of each item, again parameterized by the id.
 *
 * @param type The "type" of the action.
 * @param _idLoad See usage example
 * @param _idSuccess See usage example
 * @param _idFailure See usage example
 * @returns An instance of LoadingActions class that bundles together actions, selectors and reducers.
 * @example
 *  export const fetchItem = createIdLoadingActions(
 *    'Fetch Item',
 *    // An id field is already included in each of LoadAction, SuccessAction, FailureAction
 *    load<{}>(),
 *    success<{ item: object }>(),
 *    failure<{}>()
 *  );
 *
 *  // Dispatch load action
 *  const id = "123";
 *  this.store.dispatch(fetchItem.idLoad({ id }));
 *
 *  // Using ngrx's createFeatureSelector to select the feature slice from global store.
 *  const selectState = createFeatureSelector<SimpleState>(SIMPLE_FEATURE_KEY);
 *  const selectLoadingStates = createLoadingStatesSelector(selectState);
 *
 *  const fetchItemSelectors = fetchItem.createIdSelectors(selectLoadingStates);
 *
 *  // Observe the loading state.
 *  this.store.select(fetchItemSelectors.state(id));
