 @header NKDExtendedCode39Barcode.h

 Extended Code 3 of 9 uses the same encoding scheme as its parent Code 3 of 9, but it utilizes two-character combinations
to expand the range of encodable characters to include lower-case alphabetical characters and more punctuation and diacriticals.
 This subclass of NKDCode39 implements this encoding scheme.

 @discussion Extended Code 3 of 9 is the same encoding scheme as Code 3 of 9, except that it can encode a wider
             range of characters, including lower-case alphabetical characters by using two-character combinations
