/**
* Dropbox module for Dokeos
* Classes for the dropbox module.
*
* 3 classes are defined:
* - Dropbox_Work:
* . id
* . uploader_id => who sent it // RH: Mailing: or mailing pseudo_id
* . uploaderName
* . filename => name of file stored on the server
* . filesize // RH: Mailing: zero for sent zip
* . title => name of file returned to user. This is the original name of the file
* except when the original name contained spaces. In that case the spaces
* will be replaced by _
* . description
* . author
* . upload_date => date when file was first sent
* . last_upload_date=> date when file was last sent
* . isOldWork => has the work already been uploaded before
*
* . feedback_date => date of most recent feedback // RH: Feedback
* . feedback => feedback text (or HTML?) // RH: Feedback
*
* - Dropbox_SentWork extends Dropbox_Work
* . recipients => array of ["id"]["name"] lists the recipients of the work
* // RH: Mailing: or mailing pseudo_id
* ["feedback_date"]["feedback"] // RH: Feedback
* - Dropbox_Person:
* . userId
* . receivedWork => array of Dropbox_Work objects
* . sentWork => array of Dropbox_SentWork objects
* . isCourseTutor
* . isCourseAdmin
* . _orderBy =>private property used for determining the field by which the works have to be ordered
