DateTime::Event API suggestion

[fglock]

DateTime::Event API suggestion, 
based loosely on the DateTime::TimeZone API:

my $ev_sr = DateTime::Event->new( 
  name => 'Sunrise/sunrise' );
my $ev_ss = DateTime::Event->new( 
  name => 'Sunrise/sunset' );
my $ev_ea = DateTime::Event->new( 
  name => 'Easter' );

my $dt_set = $ev_sr->as_set;
my @dt_ary = $ev_sr->as_list( during => $dt_span );

print $ev_sr->name;  # 'sunrise'
print $ev_sr->freq;  # 'daily'  (?)

$next_sr = $ev_sr->next_for_datetime( $dt );

.. and so on.
