Usually :source:`porcupine/__main__.py` calls this function and you
don't need to call it yourself. This function can still be useful if
you want to run Porcupine minimally from another Python program for
some reason.
The *window* argument can be a tkinter root window or a ``Toplevel``
widget.
Example::
import tkinter
import porcupine
root = tkinter.Tk()
porcupine.init(root)
root.protocol('WM_DELETE_WINDOW', porcupine.quit)
root.mainloop()
