Summary of Change/Fix

Added an enhancement for batch lookups for courses and instructor information for REST API service. Can now search courses and instructors in batches. using /courses/<specify_courses_separated_by_semicolon> and /instructors/<specify_instructors_separated_by_semicolon>. In addition, invalid endpoints are handled in /all endpoint. Ex: when specifying a query with an invalid query name, /courses/all?instructor=mikes

Single course/instructor search returns an object while multiple course/instructor search returns object with key-value pair. Key is course/instructor identifier and value is Course/Instructor object.

Improvement: getCourse function can be combined with getCourses. That way Graphql course query can take an array of strings.
