In many `DataFrame.to_foo` functions I can specify that I don't want to write the index

```
>>> help(df.to_csv)

Write DataFrame to a comma-separated values (csv) file

Parameters
----------
...
index : boolean, default True
    Write row names (index)
...

```

Does similar functionality exist for `DataFrame.to_hdf`? I would like to not store the index in the PyTables table.
