Calculations about criminal tendency might better be done at each step

[mariopaolucci]

Currently, we make a bulk calculation of the criminal tendency and other stats once per year:

PyPROTON-OC/protonoc/simulator/model.py

Lines 247 to 249 in be8ae0f

	if (self.tick % self.ticks_per_year) == 0 or self.tick == 1:
	self.calculate_criminal_tendency()
	self.calculate_crime_multiplier() # we should update it, if population change

We could do it every year. However, this would better be delayed until we come out clean with the Netlogo comparison.
