    File-local definition of ResourceManager instance holder for use in cases
    where the class is used across library boundaries, in which case additional
    care must be done to ensure a single static instance.

    Usage: typedef the resource manager with Implementation::ResourceManagerLocalInstance
    as a first type and then include this file in a _single_ *.cpp file.

    This symbol is always exported.
