StaticAnalysisTool perform complex check security rules and best practices
The BackTestingFramework would need to be sophisticated enough to understand the context of each historical code snapshot, interpret results accurately, and provide meaningful metrics on the tool's performance over time.

=======================================
In this example, the NetworkMonitor class sets up a raw socket to capture packets. It has methods for processing each packet (process_packet), detecting anomalies (detect_anomalies), and reporting any anomalies found (report_anomaly). @Floydniner,
