CLI Request: Add support to show the lecturer who created exams

At the moment, with an exam you can do exam.getModule().getLecturer() but when multiple lecturers are added to a module, this will not work as only one of them would have created the module. There will need to be a field added to exam and in the schema. Then update the queries.

But that change with multiple lecturers will be a breaking change, so will not be until version 2.0.0 at least
