There should be a way to get the contents of a Data object in hexadecimal form.
The description methods do not provide that, as it was the case with NSData:
Of course I can cast to NSData
but it would be nice to have a "native" method. Suggestions:
- description returns a hex dump, or
- debugDescription returns a hex dump, or
- a new hexEncodedString method, similar to the existing Base64 methods.
