Move selection manager extras to separate package.
Tighten up public interfaces of classes.
Move BandController and GestureSelector to different package in-part to eliminate access
to <default access> methods on Selection. Goal is to force all mutation operations through
SelectionManager so that change notfication can be rationalize
(and by "rationalized" I mean understandable).
Eliminate documentsui dependency in GridModel.
Eliminate another Java 8 dependency (IntPredicate). Consolidate w/ SelectionPredicate.
Don't implement listener interfaces directly in top level classes. use inner classes.
