* Clarifies the roles of objects for getting presentation display 
availability. (#370)

Specifically:

- Each PresentationRequest has at most one presentation display 
availability and a presentation availability promise.
- The former is set to a PresentationAvailability object the first 
time it's needed.
- The latter is set to a new Promise the first time it's needed.
- Clarified text description applies to the case in the new step 5.
