Need a way to listen to events from models currently in the collection

[bengourley]

// create a new collection
var c = new Collection(serviceLocator)

// propagate the 'change' and 'reset' events from the model
c.propagateEvents([ 'change', 'reset' ])

// can now listen to propagated events prefixed with `model:`
c.on('model:change', function (model, args) {
})

[bengourley]

should any of these be on by default?
