Comunica Assign Sources Exhaustive Optimize Query Operation Actor

An Optimize Query Operation actor that converts every quad pattern in the query to a union of quad patterns per source. It will similarly handle property paths.

If only a single source is being queried over, it will attempt to assign the whole query operation to the source if the source supports such operations. Otherwise, it will fallback to the union-based approach.

This module is part of the Comunica framework, and should only be used by developers that want to build their own query engine.
