"Reservations" screen for students.
- Efficiency improvements
- Information about all slots and consumed_uniqueperiods rerieved once,
even if there are multiple resources which employ slots to control
access.
- User interface improvements in the case where there are many possible
slots to choose from. If more than a single possible slot, display
menu to show current reservation, or search for reservations in a
date/time range, or show all possible.
