Detailed Description

A ExternalSemaSource multiplexer that prioritizes its sources.

This ExternalSemaSource will forward all requests to its attached sources. However, unlike a normal multiplexer it will not forward a request to all sources, but instead give priority to certain sources. If a source with a higher priority can fulfill a request, all sources with a lower priority will not receive the request.

This class is mostly use to multiplex between sources of different 'quality', e.g. a C++ modules and debug information. The C++ module will provide more accurate replies to the requests, but might not be able to answer all requests. The debug information will be used as a fallback then to provide information that is not in the C++ module.
