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.
