Queries for a slice of data identified by a start point (inclusive) and end point (exclusive). Returns all {@link StaticBuffer}s that lie in this range up to the given limit.
If a SliceQuery is marked static it is expected that the result set does not change. @author Matthias Broecheler (me@matthiasb.com)
