A class representing a set of TIFF tags. Each tag in the set must
have a unique number (this is a limitation of the TIFF
specification itself).
This class and its subclasses are responsible for mapping
between raw tag numbers and TIFFTag
objects, which
contain additional information about each tag, such as the tag's
name, legal data types, and mnemonic names for some or all of ts
data values.
