Description
This module seeks to provide a simple method for pushing sequence changes
back to a Sequence Database - which can be an SQL compliant database, a file
based database, AceDB, etc.

Methods description
write_seqcode    nextTop
  Title   : write_seq
  Usage   : write_seq(\@updatedseqs, \@addedseqs, \@deadseqs)
  Function: updates sequences in first array,
            adds sequences in the second array,
            and removes sequences in the third array.
  Example :
  Returns :
  Args    : arrays of sequence objects that must be obtained from
            Bio::DB::UpdateableSeqI.
_add_seqcodeprevnextTop
 Title   : _add_seq
 Usage   : _add_seq($seq)
 Function: Adds a new sequence
 Example : 
 Returns : will throw an exception if
           sequences accession number already exists
 Args    : a new seq object - should have an accession number
_remove_seqcodeprevnextTop
 Title   : _remove_seq
 Usage   : _remove_seq($seq)
 Function: Removes an existing sequence
 Example : 
 Returns : will throw an exception if
           sequence does not exists for the primary_id
 Args    : a seq object that was retrieved from Bio::DB::UpdateableSeqI
_update_seqcodeprevnextTop
 Title   : _update_seq
 Usage   : _update_seq($seq)
 Function: Updates a sequence
 Example : 
 Returns : will throw an exception if
           sequence is out of sync from expected val.
 Args    : a seq object that was retrieved from Bio::DB::UpdateableSeqI

Methods inherieted from Bio::DB::RandomAccessITop
get_Seq_by_idTop
 Title   : get_Seq_by_id
 Usage   : $seq = $db->get_Seq_by_id('ROA1_HUMAN')
 Function: Gets a Bio::Seq object by its name
 Returns : a Bio::Seq object
 Args    : the id (as a string) of a sequence
 Throws  : "id does not exist" exception
get_Seq_by_accTop
 Title   : get_Seq_by_acc
 Usage   : $seq = $db->get_Seq_by_acc('X77802');
 Function: Gets a Bio::Seq object by accession number
 Returns : A Bio::Seq object
 Args    : accession number (as a string)
 Throws  : "acc does not exist" exception
Methods inheirited from Bio::DB::SeqITop
get_PrimarySeq_streamTop
 Title   : get_PrimarySeq_stream
 Usage   : $stream = get_PrimarySeq_stream
 Function: Makes a Bio::DB::SeqStreamI compliant object
           which provides a single method, next_primary_seq
 Returns : Bio::DB::SeqStreamI
 Args    : none
get_all_primary_idsTop
 Title   : get_all_ids
 Usage   : @ids = $seqdb->get_all_primary_ids()
 Function: gives an array of all the primary_ids of the 
           sequence objects in the database. These
           maybe ids (display style) or accession numbers
           or something else completely different - they
           *are not* meaningful outside of this database
           implementation.
 Example :
 Returns : an array of strings
 Args    : none
get_Seq_by_primary_idTop
 Title   : get_Seq_by_primary_id
 Usage   : $seq = $db->get_Seq_by_primary_id($primary_id_string);
 Function: Gets a Bio::Seq object by the primary id. The primary
           id in these cases has to come from $db->get_all_primary_ids.
           There is no other way to get (or guess) the primary_ids
           in a database.

           The other possibility is to get Bio::PrimarySeqI objects
           via the get_PrimarySeq_stream and the primary_id field
           on these objects are specified as the ids to use here.
 Returns : A Bio::Seq object
 Args    : accession number (as a string)
 Throws  : "acc does not exist" exception
