Fluid simulations

I have refreshed several fluid simulations projects, based on c++ and Qt (Qt is my primary toolkit). You can find they on my github:

• https://github.com/ppiecuch/Shallow-water-fluid-simulator.git
• https://github.com/ppiecuch/flowed
• https://github.com/ppiecuch/FluidSolver

They are self-contained - you need only Qt SDK (tested with Qt 5.6) installed. Should work both on OS X and Windows.
