 * NAME:        TIL_DeepSocketHandler.h ( TIL Library, C++)
 *
 * COMMENTS:    This class handles reading the interface for reading an image
 *              from a socket.  The class will read messages from the socket
 *              and send the data to the reader.
 *              The class assumes that the initial connection has been made and
 *              that the deep reader is configured to accept data.
