=head2 is_single_sequence

  Title   : is_single_sequence
  Usage   : if($splitloc->is_single_sequence()) {
                print "Location object $splitloc is split ".
                      "but only across a single sequence\n";
	    }
  Function: Determine whether this location is split across a single or
            multiple sequences.
  Returns : TRUE if all sublocations lie on the same sequence as the root
            location (feature), and FALSE otherwise.

=head2 seq_id

  Title   : seq_id
  Usage   : my $seqid = $location->seq_id();
  Function: Get/Set seq_id that location refers to
  Returns : seq_id
  Args    : [optional] seq_id value to set

=head2 coordinate_policy

  Title   : coordinate_policy
  Usage   : $policy = $location->coordinate_policy();
            $location->coordinate_policy($mypolicy); # set may not be possible
  Function: Get the coordinate computing policy employed by this object.

            See Bio::Location::CoordinatePolicyI for documentation about
            the policy object and its use.

            The interface *does not* require implementing classes to accept
            setting of a different policy. The implementation provided here
            does, however, allow one to do so.

            Implementors of this interface are expected to initialize every
            new instance with a CoordinatePolicyI object. The implementation
            provided here will return a default policy object if none has
            been set yet. To change this default policy object call this
            method as a class method with an appropriate argument. Note that
            in this case only subsequently created Location objects will be
            affected.

  Returns : A Bio::Location::CoordinatePolicyI implementing object.
  Args    : On set, a Bio::Location::CoordinatePolicyI implementing object.

=head2 to_FTstring

  Title   : to_FTstring
  Usage   : my $locstr = $location->to_FTstring()
  Function: returns the FeatureTable string of this location
  Returns : string
  Args    : none
