cmta command for creating a new course repo

[thinkmorestupidless]

When delivering the CMT workshop in Rotterdam we immediately came across the problem of having to explain to attendees how to create a new course: what structure, directory names, name of the course-management.conf and it's structure and contents... all this would be much easier if there were a command like:

cmta new course-name

which could be issued and which would create a new directory (called course-name in this case) and which would have a couple of example exercises to work from which all have the correct structure (perhaps just use our simple-repo sbt course 🤷
