=head1 VERSION

Version 0.09

=cut

our $VERSION = '0.09';

=head1 SYNOPSIS

=head1 DESCRIPTION

  This object gives access to the sequence features ( conserved motif, repeat, CpG island,
  TFBS and TSS annotation ).

=head1 AUTHORS

  Tibor Nagy, Godollo, Hungary and Endre Sebestyen, Martonvasar, Hungary

=head1 METHODS

=head2 new

  $seqfeat = Bio::DOOP::SequenceFeature->new($db,"112");
 
  You can create the object with the new method.
  The arguments are the following : Bio::DOOP::DBSQL object, sequence_feature_primary_id
