No provision for multiple names, dates, etc

[jepst]

For individuals that may have multiple tags for alternate names, the name() function returns only the last such encountered tag. To avoid breaking existing code, I'd propose extending this so that multiple such tags can be extracted, either with separate functions (e.g. names(), births()) or an optional flag to the existing functions, that would return all names and birthdays. If there is interest in this, I'd be happy to provide a pull request.
