title: Renaming a table in pandas hdfstore
body: <p>I am using pandas to join several huge csv files using HDFStore. I'm merging all the other tables to a base table, <code>base</code>. Right now I create a new table in the HDFStore for the output of each merge, which I call <code>temp</code>. Then I delete the old base table. Finally, I copy <code>temp</code> to <code>base</code> and start the process over again on the next table I need to join.</p>
  
  <p>This would be much more efficient if I could simply rename <code>temp</code> to <code>base</code>. Is this possible?</p>
