No write to file example

[federicomartinlara1976]

The hello_world.cc example has no use of write to csv file method.

I didn't want to write to a file in hello world because I was cautious about messing up the user filesystem which I don't know anything about. Code sample for all functions are in the docs here: https://htmlpreview.github.io/?https://github.com/hosseinmoein/DataFrame/blob/master/docs/HTML/DataFrame.html

Anyway, i have checked and this format for csv is not suitable for my example. Thank you

You probably want the csv2 format which is similar to Pandas csv format

Thank you. I'll test the format that recommend.
