=head1 NAME

Bio::EnsEMBL::SimpleFeature - A simple feature with a location and label

=head1 SYNOPSIS

  use Bio::EnsEMBL::SimpleFeature;

  $feature = Bio::EnsEMBL::SimpleFeature->new(
    -start         => 100,
    -end           => 220,
    -strand        => -1,
    -slice         => $slice,
    -analysis      => $analysis,
    -score         => 58,
    -display_label => 'EponineTSS',
    -dbID          => 1230,
    -adaptor       => $adaptor
  );

=head1 DESCRIPTION

This is a simple feature which extends the Feature class to add
display_label and score attributes.

=head2 new

  Arg [DISPLAY_LABEL]: The label assigned to this simple feature
  Arg [...]  : Named arguments passed to superclass
  Example    : $feature = Bio::EnsEMBL::SimpleFeature->new
                        (-start    => 1,
                         -end      => 100,
                         -strand   => 1,

                         -analysis => $analysis,
                         -adaptor => $adaptor,
                         -dbID    => 10,
                         -display_label => 'EponineTSS',
                         -score => 100);
  Description: Constructs a new Bio::EnsEMBL::Feature.  Generally subclasses
               of this method are instantiated, rather than this class itself.
  Returntype : Bio::EnsEMBL::Feature
  Exceptions : Thrown on invalid -SLICE, -ANALYSIS, -STRAND arguments
  Caller     : general, subclass constructors
  Status     : Stable

  Arg [1]    : (optional) string $value
