// In this assignment, you will be creating a calendar application that will load and save data. An example of loading and saving data has been provided.
// This calendar application will accept multiple event types which will be represented by their own class types.
// You will be dealing with Appointments, Meetings, and Reminders.
// Task 1:
// Create new classes that will represent the calendar items that you will be using.
// Each of your classes will inherit from the CalendarItemBase abstract class.
// Reminders have already been created as an example.
// Task 2:
// Define Your Data
// Appointments need to be assigned a start date and time, an end date and time, and a location.
// Meetings need to be assigned a start date and time, an end date and time, a location, and attendees. You can decide what data you need for attendees.
// Reminders need to be assigned a start date and time.
// Hint: Use inheritance to make your life easier.
// Task 3:
// Add the missing code to the ReminderRepository. Hint: Look for instances of NotImplementedException.
// Create repository classes for Appointments and Meetings. Use the ReminderRepository as an example.
// Task 4:
// We want our application to load data and to save data. The process for reminders has already been created. You will need to do the same thing
// for the other data types.
