Created a method to check if calculations should take place.

Browse source 
Created a method to check if calculations should take place
taking into consideration what changed on the model. if the
model changes *everything*, them, all calculations should
be done, but if just some of the columns of the model are
changed, only those columns should trigger an visual update
on the items.

In theory this patch looks right, but something is wrong (
calculations are not being made. ), so I'll commit this any
how, and fix on the next commit.
