Comment(by mvngu):
The updated patch addresses rbeezer's comments on sanity checking the
value of the encryption/decryption key. The sanity checking is done in the
callable `__call__()` of the class `ShiftCryptosystem`. I have added
doctests to that callable. Currently, methods beginning with an underscore
"`_`" don't show up in the reference manual, so I have also added the
doctests for checking key value to the docstring for the class
`ShiftCryptosystem`. In this way, reading the reference manual for the
shift cryptosystem should make it clear (hopefully) that the value of an
encryption/decryption key must lie within the range of acceptable values,
i.e. must be within the key space.
