Has this code been tested?

[FrankyEverest]

Very interesting to propose a standalone XFOIL cpp implementation.
But in it's current form, does it work? Yes it does!!!

After some fiddling in QT, got the code to work as a QTCore (console) app. Here are the result of my test run with the Clark_Y profile that was supplied...

...very cool!

Thanks for your work in extracting this from XFLR5 code.
Much appreciated...
