 The task list feature is facilitated by 'TaskManager'. It extends a ReadOnlyTaskManager that will be used for 
 saving users' tasks. The data of the TaskManager is contained in a `TaskList` object. Additionally, it implements the following operations:
 
-*`TaskManager#addTask(Task)` -- Adds a task to the current task list and saves it to memory.
-*`TaskManager#deleteTask(int)` -- Delete an existing task from the current task list as indicated by its index and saves the change to memory.
-*`TaskManager#sortTasksBy(String)` -- Sets the comparator by which the internal TaskList is sorted to one of two preset options.

 This method only accepts the strings `"Description"` or `"Deadline"` as input and throws an error otherwise.

 These operations are exposed in the `Model` interface as `Model#addTask(Task)`, `Model#deleteTask(int)`, `Model#sortTasksBy` and `Model#getTaskList` respectively.
