> Improve docstring of mapInPandas
> * "using a Python native function that takes and outputs a pandas DataFrame"
> is confusing cause the function takes and outputs "ITERATOR of pandas
> DataFrames" instead.
> * "All columns are passed together as an iterator of pandas DataFrames"
> easily mislead users to think the entire DataFrame will be passed together,
> "a batch of rows" is used instead.
