+Opens a new window and draws `ap2t2`, the `Periodic_2_Triangulation_2`. A call to this function is blocking, that is the program continues as soon as the user closes the window. 
+ This function requires CGAL_Qt5, and is only available if the flag CGAL_USE_BASIC_VIEWER is defined at compile time.
+\tparam P2T2 a model of the `Periodic_2TriangulationTraits_2` concept.
+\param ap2t2 the 2D periodic trinagulation to draw.
