/**
 * Represents an image with Exif information. When instantiating it you have to
 * provide an image and a callback function which is called once all metadata
 * is extracted from the image.
 *
 * Available options are:
 *  - image The image to get Exif data from can be either a filesystem path or
 *          a Buffer.
 *  - tiffOffsets  (boolean) an object named "offsets" is added to exifData 
 *          and contains lot of offsets needed to get thumbnail and other things. 
 *  - fixThumbnailOffset:  node-exif corrects the thumbnail offset in order to have an offset from the start of the buffer/file.
 *  - maxEntries: Specifies the maximum entries to be parsed
 *  - ifd0MaxEntries
 *  - ifd1MaxEntries
 *  - maxGpsEntries
 *  - maxInteroperabilityEntries
 *  - agfaMaxEntries 
 *  - epsonMaxEntries
 *  - fujifilmMaxEntries
 *  - olympusMaxEntries
 *  - panasonicMaxEntries
 *  - sanyoMaxEntries
 *  - noPadding
 *
 * If you don't set the image field, you might call  exifImage.loadImage(image, callback) to get exif datas. 
 *
 * @param options Configuration options as described above
 * @param callback Function to call when data is extracted or an error occurred
 * @return Nothing of importance, calls the specified callback function instead

 * The Function.prototype.inherits from lang.js rewritten as a standalone
 * function (not on Function.prototype). NOTE: If this file is to be loaded
 * during bootstrapping this function needs to be rewritten using some native
 * functions as prototype setup using normal JavaScript does not work as
 * expected during bootstrapping (see mirror.js in r114903).
 *
 * @param {function} ctor Constructor function which needs to inherit the
 *     prototype.
 * @param {function} superCtor Constructor function to inherit prototype from.
