My solution to the problem A of the round 1A of Google Code Jam 2013
'''
Problem solution
----------------
The area of a circular ring is:
pi * (R^2 - r^2)
where R is the radius of the bigger circle and r
the radius of the other one.

'''Definire una classe PColor e una classe PImage secondo le seguenti specifiche.
La classe PColor rappresenta un pixel che puo' avere un colore RGB o essere
trasparente e deve implementare i seguenti metodi:
- Costruttore, senza argomenti, che inizializza l'oggetto come pixel trasparente.
- set_RGB(r, g, b) imposta il colore RGB dell'oggetto con i valori r,g,b e
ritorna l'oggetto.
- to_RGB() ritorna una tripla (r,g,b) che sono i valori dei canali RGB
