/**
* STUDENT PUBLICATIONS MODULE
*
* Note: for a more advanced module, see the dropbox tool.
* This one is easier with less options.
* This tool is better used for publishing things,
* sending in assignments is better in the dropbox.
*
* GOALS
* *****
* Allow student to quickly send documents immediately visible on the Course
*
* The script does 5 things:
*
* 1. Upload documents
* 2. Give them a name
* 3. Modify data about documents
* 4. Delete link to documents and simultaneously remove them
* 5. Show documents list to students and visitors
*
* On the long run, the idea is to allow sending realvideo . Which means only
* establish a correspondence between RealServer Content Path and the user's
* documents path.
