:Provided barcodes: ISBN-13, ISBN-10, ISSN

This module provides some special codes, which are no standalone barcodes.
All codes where transformed to EAN-13 barcodes. In every case, the checksum
is new calculated.

Example::

    >>> from barcode import get_barcode
    >>> ISBN = get_barcode('isbn10')
    >>> isbn = ISBN('0132354187')
    >>> isbn
    '0132354187'
    >>> isbn.get_fullcode()
    '9780132354189'
    >>> # Test with wrong checksum
    >>> isbn = ISBN('0132354180')
    >>> isbn
    '0132354187'
