// CrowdNavigation example.
// This sample demonstrates:
// - Generating a dynamic navigation mesh into the scene
// - Performing path queries to the navigation mesh
// - Adding and removing obstacles/agents at runtime
// - Raycasting drawable components
// - Crowd movement management
// - Accessing crowd agents with the crowd manager
// - Using off-mesh connections to make boxes climbable
// - Using agents to simulate moving obstacles
