As of version 0.02, hexhash() returns a hex digest starting
with the least significant byte first. For example:
Hash of "Tiger":
0 7 8 15 16 23
DD00230799F5009F EC6DEBC838BB6A27 DF2B9D6F110C7937
7 0 15 8 23 16

The print order issue was brought up by Gordon Mohr; Eli Biham clarifies with:
The testtiger.c was intended to allow easy testing of the code,
rather than to define any particular print order.
...using a standard printing method, like the one for MD5 or SHA-1,
the DD should probably should be printed first [for the example above].
