Integer input example

[timeopochin]

Hello!

I just discovered this project, it's wonderful! I've been playing around with it and I think it will be part of many of my future projects. I needed to have a way to input an integer, and I thought my implementation was worth sharing. I'm not sure if it's the sort of thing that would make sense to add to the library which is why I haven't made a pull request; but I could always try to make it part of the project in the future.

Here it is: FTXUI integer input example

It does require C++11 as I use std::stoi.

P.S. Actually, maybe it would be a good thing to add to the examples, even if it isn't part of the library itself? Let me know :)

Nice!

I tried, it worked. Maybe we can add a link to it from the wiki?
