Utilizes the PubMed tool esearch.fcgi to convert an accession number into a valid NCBI UID number.
WARNING: The powers that be at NCBI have been known to ban the IP addresses of users who abuse their servers (currently defined as less then 2 seconds between queries). Do NOT put this function in a type loop or you may find your access revoked.
Returns either a valid NCBI UID value or NULL (if there was nothing available).

## 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")Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
