 <code>UniProt.ws</code> function. Using
<code>keytypes(up)</code> we can see all the keys we can use to query
the database and with <code>columns(up)</code> we can see all the
different fields we can get in return. Our gene IDs are
EMBL-GenBank-DDBJ_CDS identifiers. For this tutorial we want to return
the keywords associated with each gene such that we can use it to group
the genes based on their function.</p>
