You might want to explain what IBM 360 style BCD is, for those of us who 
aren't intimately familiar with it.  Where do you expect the the least 
significant digit and the most significant digit to appear?  What does 
the final array format look like?  (I'm pretty sure the original IBM BCD 
didn't use Java arrays).

Explain where the digits go in an array for each of the following test 
cases:

1
12
123
1234

Where is the length of the BCD indicated?
