Feature Request: parallel agg (aggregate)

[kinghuang]

I'm interested in a parallel version of pandas.DataFrame.agg. It's similar to apply, but with multiple functions applied to the rows/columns at once.

This would be a great feature.

I opened a Pull request, which should fix this issue. At the moment only DataFrame.agg is implemented. DataFrame.groupby.agg is still missing (and some other agg functions). Feel free to test it and give feedback if something is not working.
