hum,
on my own method using the generic check digits algorithm given per GS/1, I get the same result as python-barcode:
so maybe this shall be "rebranded" as "ean_key_computation", but it's not faulty as you think
from python-barcode.

The issue is that the implementation saves the whole number plus the checksum into self.ean, but then calculate_checksum calculates the checksum for self.ean (e.g.: a string which already includes the checksum).

While this is the "expected behaviour" as per the documentation, it's obviously un-intuitive and can be improved. I'm just not sure how to improve it without breaking existing usages.

I think that #215 should fix it. Can you confirm?
