Added school_data2.py in the package. This script generates a random
instance and can be used to have smaller instances than the orignially
published one.

To use this script you need to change in school.py the line 

from school_data import *
to
from school_data2 import *

Then:

python school.py 10 2012

where now the last number is the random seed used by school_data2.py
