Abstract: Custom class for the Event entity.
5+
6+
The timeStamp and title are persistent attributes; the sectionIdentifier is transient and derived from timeStamp.
7+
* timeStamp is the date on which the event occurred.
8+
* title is displayed in the table view rows.
9+
When the default data is created in the application delegate, the title is initialized to a string representation of the date.
10+
* sectionIdentifier is used to divide the events into sections in the table view.
11+
sectionIdentifier is a string value representing the number ((year * 1000) + month). Using this value, events can be correctly ordered and grouped regardless of the actual name of the month. It is calculated and cached on demand in the custom accessor method.
