locationProcessorSource

Uses the provided value to attach the Session optional location data processing pipeline to once built. The provided Source is normally attached to when location data is required to be presented as part of image processing and de-attached once the location data is not needed anymore. Providing the Source is optional as location data is optional, it does not change the any aspect of business logic. The main advantage of providing the Source of location data is to enable certain types of location specific content such as Landmarker lenses that augment real life objects pinned to geographic co-ordinates.
