Quickstart and Deploy: simplified structure in the "embed" case
In the embed case, the directory structure generated by quickstart and expected by deploy is:
<course_dir>/Instructors/
<course_dir>/Instructors/ComputerLab/
This commit simplifies it by indentifying <course_dir> and Instructors:
<course_dir>/
<course_dir>/ComputerLab/
This structure has been successfuly in use by many instructors. Instructors can still have an overarching directory holding the above should they wish to, but they don't have to.
