* Class with static methods for Exif tags.

* This class defines the constants that represents the Exif tags

* specify an Exif tag, and they will be denoted by the pseudo-type
* {@link PelTag} throughout the documentation.
*
* Please note that the constrains on the format and number of
* components given here are advisory only. To follow the Exif
* specification one should obey them, but there is nothing that
* prevents you from creating an {@link IMAGE_LENGTH} entry with two
* or more components, even though the standard says that there should
* be exactly one component.
*
* All the methods in this class are static and should be called with
* the Exif tag on which they should operate.
