Manages a subscription callback on synchronized Image and CameraInfo topics.
CameraSubscriber is the client-side counterpart to CameraPublisher, and assumes the same topic naming convention. The callback is of type:
void callback(const sensor_msgs::ImageConstPtr&, const sensor_msgs::CameraInfoConstPtr&);
A CameraSubscriber should always be created through a call to ImageTransport::subscribeCamera(), or copied from one that was. Once all copies of a specific CameraSubscriber go out of scope, the subscription callback associated with that handle will stop being called. Once all CameraSubscriber for a given topic go out of scope the topic will be unsubscribed.
