=head1 NAME

Gedcom::Family - a module to manipulate Gedcom families

Version 1.20 - 17th September 2017

=head1 SYNOPSIS

  use Gedcom::Family;

  my @rel = $f->husband;
  my @rel = $f->wife;
  my @rel = $f->parents;
  my $nch = $f->number_of_children;
  my @rel = $f->children;
  my @rel = $f->boys;
  my @rel = $f->girls;
  $f->add_husband($i);
  $f->add_wife($i);
  $f->add_child($i);

=head1 DESCRIPTION

A selection of subroutines to handle families in a gedcom file.

Derived from Gedcom::Record.

=head1 HASH MEMBERS

None.

=head1 METHODS

None yet.

=head2 Individual functions

  my @rel = $f->husband;
  my @rel = $f->wife;
  my @rel = $f->parents;
  my @rel = $f->children;
  my @rel = $f->boys;
  my @rel = $f->girls;

Return a list of individuals from family $f.

Each function, even those with a singular name such as husband(),
returns a list of individuals holding that relation in $f.

=head2 number_of_children

  my $nch = $f->number_of_children;

Return the number of children in the family, as specified or from
counting.

=head2 Add functions

  $f->add_husband($i);
  $f->add_wife($i);
  $f->add_child($i);

Add the specified individual to the family in the appropriate position.

These functions also take care of the references from the individual
back to the family, and are to be preferred to the low level addition
functions which do not do this.
