Generate calendar of birth, death, marriage events arranged by the year, month 
and day that they occurred.  Generates a top level index by year, with actual
events stored in a separate html file for each decade.
Some properties must be set in your lifelines configuration file for this
report to run, see comments at beginning of the report for details.

Warning, this report requires lifelines version 3.0.50 or later.

         Version 1   March    2003  
         Version 2   November 2005 Support privitizing data
         Version 3   December 2005 Do html char set encoding
         Version 4   June 2006 incorporated mods by Dave Eaton (dwe@arde.com) May 2006

This program was inspired by similar efforts by Mitch Blank (mitch@ctrpnt.com)
but without ever seeing the code he used to do a similar thing.

The code used in cron.ll is very similar to anniver.ll.  Other than the
sort order and print out details, the two programs share about 3/4 of their
code.

Before using, there are a few properties that need to be customized for your
own environment so add them to your .linesrc ( or for windows lines.cfg) file.
You can also set them on the command line (like -Ianniver.htmldir=/tmp/foo)
The properties that are looked up are:
   user.fullname -- name of the database owner
   user.email -- email address of the db owner
   cron.htmldir -- path to the directory to store results in
                     e.g. /home/joe/genealogy/html
                     (program expects a subdir in this directory with the name
                     of the database in it.)
   cron.backgroundimage -- path to the background image,
                 no image if not defined.
                 e.g. ../../image/crink.jpg
                 this places image at the same level as /home/joe/genealogy/html
   privatization:  This report respects 2 levels of privatization
       1. if a record "RESN confidential" exists on an individual they are
          skipped (as this report is designed to be shared, this seems
          like a reasonable default)
       2. skip anyone estimated to be living

   History.
      Version 2 Add code to allow respecting privatized data.
      Version 3 switch from baptism() to get_baptism() for wider coverage
                use translation tables to convert data to properly 
                escaped html.  This is very codeset dependent.
     Version 4   added changes by Dave Eaton (dwe@arde.com)
         These were actually changes to anniver4, but merged here too.
         Added "firstyear" that events may be on the calendar
         Added "includedeath" check to drop deaths if those are not desired
         Added ability to generate report for descendants of more than one
             individual
         Added ability to generate report only for living people 
             (omitting confidential if desired)
