### Examples

         ## The two returns from genbank should be the same
         xdoc <- genbank("U03397",type="accession",disp="data")
         x <- accessionToUID("U03397",db="genbank")
         xdoc <- genbank(x, type="uid",disp="data")

         ## Can handle multiple inputs
         y <- accessionToUID("M16653","U892893",db="genbank")
