RPS

This is a cli implementation of Rock Paper Scissor (in Italian 'Morra Cinese').

How to play

You have to launch the program with your choice, for example:

./RPS.py P

Remember:

* `P` stands for paper
* `R` accounts for rock
* `S` is for scissor

Next simple improvements: Use also "paper" or "Paper" for 'P' and so on..

Future version:

- version 1: iteractive version - using coroutines
- version 2: improving game strategy - not a simple random choice
- version 3: learn from player

experimental version: Introduce "Spok" and "Lizard"
