Given the two collections users and courses. And another sub-schemas of lectureSchema, fileSchema, and questionSchema.

Implement the following methods:

• add a new user with (fullname, email, password, and location with the following value [-91.96731488465576, 41.018654231616374])
• add a new course with (code, title). Fill out the created_by property from the previous method (prefixed hard-coded values).
• add a new lecture with (title, description).
• add a new question with (question).
• use the aggregation pipeline to get all questions for a specific course and lecture. (with pagination).
• use the aggregation pipeline to get one question by ID, for a given course ID and lecture ID.
• update a question by ID, for a given course ID and lecture ID, and extend the due date for another day.
• update all questions questions, for a given course ID and lecture ID, and extend the due date for another day.
• delete one question by ID, for a given course ID and lecture ID.
• find the nearest 10 users that match a certain set of hobbies, using 2d index.
