APPENDIX

       The rest of the documentation details each of the object methods. Internal methods are
       usually preceded with a _

   new
         Title   : new
         Usage   : $range1 = Bio::LiveSeq::Range->new(-seq => $obj_ref,
                                                      -start => $beginlabel,
                                                      -end => $endlabel, -strand => 1);

         Function: generates a new Bio::LiveSeq::Range
         Returns : reference to a new object of class Range
         Errorcode -1
         Args    : two labels, an obj_ref and an integer
                   strand 1=forward strand, strand -1=reverse strand
                   if strand not specified, it defaults to 1
                   the -seq argument must point to the underlying DNA LiveSeq object

   valid
         Title   : valid
         Usage   : $boolean = $obj->valid($label)
         Function: tests if a label exists AND is part of the object
         Returns : boolean
         Args    : label
