/*
* Method: AnnotateImages
*
* Description: This method can be used to query the Google Cloud Image Intelligence API with a batch of
* images and run image detection and annotation on these images.
*
* Parameters:
* - imageRequests (AnnotateImageRequestList): List of all the individual AnnotateImageRequests that will
* be sent to the Image Intelligence API.
*
* - APIKey (String): Implicity required paramter which should be set through the constructor when
* creating an object of this class. For more details about the Google API Key please see:
* https://developers.google.com/places/web-service/get-api-key
*
*
* Return: If the query is successful, then the method will return a tuple of two items. The first is an
* AnnotateImageResponseList object with image identification and annotation corresponding to each image
* request from the request list. The second element is a ResponseStatus object indicating the status of
* the query along with the appropiate HTTP code. Since the HTTP query and the indentification are both
* performed asynchronously, the return object is wrapped in Task<>.
