Reset index function

[dansbits]

Is there a function on the data frame similar to the pandas reset_index method for adding the values in the index to the dataframe. I often find myself wanting to re-incorporate the index back into my dataframe after using group_by.

I don't see anything and wanted to check before trying to add it.

Should be a good addition. How will the new vector that the index will create be named? Also, the new index that the dataframe will get will be numbered from zero right?
