/**
 * Create two event lists with full info from all pages:
 * 1. Favorite events list (favorites)
 *   - in order from getFavoriteEvents()
 * 2. Non-favorite events list (other)
 *   - in order from getAllEvents() excluding favorite events
 *
 * To get full event info use getEventById()
 *
 * Requirements:
 * 1. Load data in fastest way possible (using concurrency)
 * 2. Filter events in O(n), n - events count
