Features

:information_source: Notes about the command format:

• Fields after deadline/event descriptions should be followed by a / and a preposition such as by or at with no whitespace in between. The subsequent field takes in a date in the YYYY-MM-DD format with a whitespace before the field. Any other date format is not able to be accepted.
  e.g. deadline Homework /by 2020-08-08 creates a deadline for homework at 2020-08-28, but using 2020-28-08 will not be accepted.

• The commands done and delete need to be followed by a whitespace and an integer greater than 0 and less than or equals to the size of the task list.
  e.g done 1 will mark the first task as done, delete 1 will mark the first task as deleted from the list but done 0 or delete will both neither be accepted inputs.

• The task-identifying commands todo, deadline and event must have text input after these fields.
  e.g. todo Read a book is an accepted input, but todo is not

• The input and commands are case sensitive.
  e.g. todo Read a book is an accepted input, but Todo read a book is not
