CloudServerCloudZoo(zooUrlopt, accessToken)

This class is responsible for managing and loading models from a cloud-based AI model zoo, for inference in the cloud. It handles model discovery, fetching model information, and loading models for use. Use loadModel() to instantiate and configure a model for use. Various utility functions are available to interact with the cloud zoo.
