Hi, thanks for your work developing pandas. I'd like to request a feature to add an ungroup() method for grouped data frames. It's related to this StackOverflow where I've developed a hack to extract using the .obj to pull out the original data frame from the grouped data frame.

However, it would be helpful to have a method developed, which would do the extraction to prevent users from depending on my hack.

>>> dat_1 = df.groupby("category_2")
>>> dat_1
<pandas.core.groupby.generic.DataFrameGroupBy object at 0x7fce78b3dd00>
>>> dat_1.obj
    order_date          category_2     value
