Toplevel Child Window example (Tkinter/Python)

''' tk_Toplevel2.py
a toplevel child window has options like color, height, and width
size and position it with geometry()
lift and lower it with respect to other windows
you can exit a toplevel window alone
or it will exit as the main/root window exits
