A day is used to group items in the schedule. Whilst the day can be determined by checking the start and end dates for the sessions, it was decided to create an object graph to remove the need to perform those queries.
A section is a group of sessions. For example, a section represents Tuesday afternoon. Within a section, there are sessions.
A session is a time block where something is happening in the conference. This has a start time and an end time. A session can have one or more session items.
The session item represents an entry that is shown on the schedule. It can have different types, e.g. talk or workshop.
This class holds a setting that is used by the application.
CoreData is used to store the data locally in the application.
