Synopsis
  $slice =
    $sa->fetch_by_region( 'chromosome', 'X', 1_000_000, 2_000_000 );

  my $projection = $slice->project("clone");

  foreach my $projection_segment (@$projection) {
    print( "  from_start ", $projection_segment->from_start(), "\n" );
    print( "  from_end   ", $projection_segment->from_end(),   "\n" );
    print( "  to_Slice   ",
      $projection_segment->to_Slice()->name(), "\n" );
  }
Description
The ProjectionSegment is a helper object to make the arrays returned by
project more accessible. Instead of writing $segment->[0], $segment->[1]
or $segment->[2] its possible to use the more descriptive notation of
$segment->from_start(), $segement->from_end(), $segment->to_Slice().
