[P0] Database Utilities

[SirajChokshi]

Create a new directory in ./api/utils named ./api/utils/mock-data/

In this folder write scripts to generate each type of data model available (currently/soon to be Reviews, Courses, and Careers) and save them to the database.

e.g. node ./api/utils/mock-data/courses.js <number> puts <number> randomly generated courses into our collection of courses.

You can access command line arguments from node by using the process.argv object.
