Backbone.SoftModel

soft-model.js

/**
Extend Backbone.SoftModel and then bind to the 'soft:change' event.
It will only fire once given a sequence of rapid-fire changes.
This avoids for example having multiple redundant renders,
which can be a performance killer. That way you don't have to
splatter your code with speculative {silent:true}s.

Warning!
This code is untested. This is just exploring an idea.
