Review comment:
I agree that this seems to fit well into `_inferSchema` &
`_createFromRDD`, although we still would need some way to discern between an
rdd of DataFrames and other types when the user provides a schema (and we don't
want to peek into the first item).
Do you think it would be better to move the pandas flag into
`_createFromRDD`?
