 * Requirements

 * this new type of object
 * 
 *    let myCourse = Course.create();
 * 
 * and then we should be able to get and set
 * serveral properties (title, description, tags)
 * on this instance
 * 
 *    myCourse.set('description', 'In this course, we'll learn about cats!')
 * 
 * Additionally, you need to make a class method
 * for taking abbreviated programming language 
 * names, and expanding them.
 * 
 *    Course.languageName('js') // returns "JavaScript"
 * 
 *  Keep in mind that this function needs to be on the
 *  class, not on instances of the class.
