[drfidel]

**Is your feature request related to a problem? Please describe. **
When the Teacher user logs in, Teacher dashboard should be displayed with a list of enrolled courses and once user selects a given enrolled course, he/she should be able view the contents of the course and also the overview of the entire course, view their progress into the course and be able to save their progress and resume and that point.

If user selects an unenrolled course, they should be able to view the overview of the entire course without details and should be able to enroll into the course.

Also if a guest clicks to view course from the landing page, they should be able to view an introductory video / description of the course, and then ask to sign-up or login and enroll to view contents.

Course streaks will be recorded and user gets a badge when they finish a streak.

Describe the solution you'd like
Design an easy-to-use UI/UX template that seamlessly loads course details from the server.

Additional context
Views for unlogged in, for logged in not enrolled and logged in enrolled.
