Simplify recursive update prevention

[jeffbcross]

After reviewing the challenges with recursive updating with @IgorMinar, we decided we should focus on one direction of the problem right now, making sure changes to a model from protocols don't get sent back to protocols. It will be up to a protocol implementation to solve the problem in the other direction.

Binder will need to be refactored, as well as other places within the framework that are incrementing values based on number of changes that occur.
