- The documentation is cluttered enough as it is with the large number
of procedures supporting vCard 3 and 4. Split common out into the
publicly exposed bits and the private internals. This makes it obvious
which common functionality a client can expect to have exposed on the
main vcard module.
- Add documentation (WIP) on the vcard3 module.
The `unittest` library still contains a number of bare exceptions, which
now result in warnings from the compliler. Patching the standard library
to remove these warnings is outside the scope of this project, so we're
going to ignore these warnings.
