Command Line Todo List

Description

Write a command line script called tasks that allows the user to manage a list of tasks from the terminal.

Your tasks command should support the following sub-commands:

command	description	example usage
add	adds the specified task	./task.js add Finish reading Flatland
list	lists the incomplete tasks	./task.js list
complete	marks the task with id equal to <task-id> complete	./task.js complete <task-id>
delete	deleted the specified task	./task.js delete <task-id>

In this 1st version the data for your tasks should be saved to a file called tasks.json.

Specs
