Revision history for Perl extension Text::vCard.
1.93 Mon 31st Jan 2005
        - Restructured object so all nodes are stored in a hashref
          $self->{nodes} so I can get get_group to work, all other
          methods updated to reflect this.
        - added get_group() to vcard
1.92    - Added group() to Node and extract that info
          from the vcard if it is there.
1.91
        - Doc bug, said 'tels', should have been 'tel'.
1.9 
        - removed import() from docs as not used now
        - changed Node so excepts data with less than field order elements 
        e.g. N, accepts 'Jon;Smith', As well as 'Jon;Smith;Dr;' this means
        we work better according to the RFC
        - ORGs' 'unit' method requires and returns an array ref as it is
        unlimited in the number of elements it has
1.8 Fri 15th Oct 2004

          now access it as lowercase version().

1.6 Wed 13th Oct 2004

        - Lots of tests added
