Description
## Description
didUpdateFrameSignClassifications delegate method is invoked very late (almost after the sign has gone out of frame)
## Goal
it would be much more useful to app developers/end users if the method is invoked as soon as a sign is classified; so we can give drivers some time to react to the detection of a sign. Currently, it's almost too late to produce real time alerts.

Research direction
Start by locating the didUpdateFrameSignClassifications delegate method and the sign-classification flow that invokes it. Trace when a sign becomes classified versus when the delegate is called; done means the callback occurs promptly after classification while preserving the existing delegate behavior.
