Query<C extends GpsPointsView<GpsPoint>, R extends QueryResult> class abstract

Abstract generic ancestor class for queries parametrized for collection type C and result type R.

Since queries may have specific implementations for particular collection types, they are generics parametrized for collection type.

The goal is to be able to send queries to a separate isolate and get the results back efficiently. This requires the Query children to store internally a representation that is cheap to transfer over an isolate port.
