Tasks

Completed 1.

Tasks have name, descriptions, and difficulty levels. Can be created, edited, and deleted from the project show page.
Are a nested resource.

1. Create the Task model and controller. A task should have a name, description, and difficulty_level (which can just be an integer). Projects should "have many" tasks. From the project “show” page, you should be able to see all of the tasks for the project, their difficulty level, and a link to edit each one.
