+FirecrawlApp Module
+
+This module provides a class `FirecrawlApp` for interacting with the Firecrawl API.
+It includes methods to scrape URLs, perform searches, initiate and monitor crawl jobs,
+and check the status of these jobs. The module uses requests for HTTP communication
+and handles retries for certain HTTP status codes.
+
+Classes:
+    - FirecrawlApp: Main class for interacting with the Firecrawl API.
