 *       "tree1"    - By yours truely, jjones@nas.nasa.gov
 *
 *   This report works only with the LifeLines Genealogy program
 *
 *   This report creates one of the following timeline charts:
 *
 *      1. Ascii timeline showing birth, marriage, and death events of
 *         selected individuals; shows which individuals were contemporaies.
 *
 *      2. IN PROGRESS
 *
 *   User selects individual to base the chart on; then selects from
 *   the following sets:
 *
 *              parents,
 *              children,
 *              spouses,
 *              ancestors,
 *              descendents,
 *              everyone
 *
 *   User selects start date (e.g. 1852) and end date for graph; as well as
 *   graph size (80 or 132 col).
 *
 *   Note: If an indi is "alive" for more than 100 years, this is flagged as
 *   "uncertain", with a question mark in the graph after 100 years from birth.
 *   One should check these individuals to determine where they are really
 *   that old, or if one can determine an approxmate date of death, etc.
 *
 *   Additional functionality will be added as soon as LL version 2.3.5
 *   is released.
 *
 *   Sample output follows (start=1800; end=2000; 80 columns):

         Name           1800 1820 1840 1860 1880 1900 1920 1940 1960 1980 2000
