 @header NKDMOdifiedPlesseyHexBarcode

 This is an extension of the Plessey code. The Plessey specification sets out the encoding scheme for
 numeric data, but leaves the other bar combinations open. This is the most common use of the open
 combinations - to encode the letters A through F, allowing the use of Hex notation to represent 0-255
 in a two character combination.
