/**
* This script displays a list of the users of the current course.
* Course admins can change user perimssions, subscribe and unsubscribe users...
*
* EXPERIMENTAL: support for virtual courses
* - show users registered in virtual and real courses;
* - only show the users of a virtual course if the current user;
* is registered in that virtual course.
*
* Exceptions: platform admin and the course admin will see all virtual courses.
* This is a new feature, there may be bugs.
*
* @todo possibility to edit user-course rights and view statistics for users in virtual courses
* @todo convert normal table display to display function (refactor virtual course display function)
* @todo display table functions need support for align and valign (e.g. to center text in cells) (this is now possible)
* @author Roan Embrechts, refactoring + virtual courses support
* @author Julio Montoya Armas, Several fixes
