Flex Grid

Hey,
great work on starting to port the awesome foundation for apps over!!!
I am looking at this for the first time and am very impressed.

I just wanted to ask if the grid from foundation for apps is also available?
I would really like to use it, or would you suggest to use another solution for that, like for instance https://github.com/tcoopman/react-flexbox or just a global stylesheet with the grid classes?

Cheers
