PySide

Recently, FreeCAD has switched internally to use PySide instead of PyQt. That change was mainly done because of the licenses, PySide having an LGPL license which is more compatible with FreeeCAD. Other than that, PySide works exactly the same way as PyQt, and in FreeCAD you can usually use any of them, as you prefer. If you choose to use PySide, just replace all "PyQt" in the example code below with "PySide".
