- * Helper class: stores a Task
- *
- * This class stores data specific to a Task:
- * -the task caption/title (list layout and title layout)
- * -the lists of Service (UIDs) & MIMEs associated with this task
- * -the MIME label
- * -a list of Services & MIMEs objects (and their associated application list) that correspond to the list
- * of Services & MIMEs associated with the task
- * -a list of applications (CAppHelper) that are associated with this task
- * -the UID and list index of the default application for the task, in the list(s) above.
- *
- * How this works:
- * The Service & MIME pairs associated with the task are those pairs for which changing the default application for the
- * task will have an impact: the new default becomes the default application for all these pairs, if applicable.
- * The list of candidate default applications is build from the Service & MIME pairs associated with the task: any
- * application that can handle at least one pair, is added to the list. The score corresponds to the number of pairs an
- * application is able to handle (the better the score, the more suitable the application is for the task).
- * When a new application is made default, it is also made default for Open + the MIME label. This way we can retrieve
- * the default application for the task, to display it to the user.
- * The list of Services & MIME objects are instances of CServiceMime that correspond to the list of Services & MIMEs that
- * are associated with the task (the associated Services & MIMEs is a "theoretical" list, while the CServiceMime list
- * is a list of Services & MIMEs that were found in the system. The Services & MIMEs in this object list is a subset of
- * the associated Services & MIMEs. The reunion of all Applications lists associated with each CServiceMime object in the
- * list is going to be same as the list of Applications that are associated with the Task.
- * When a new default application is selected for the task, this new default is saved in 2 ways:
- * -the new default application is made default for the Open service and the MIME label. This way, we can retrieve next
- * time the default application for the task. There is no danger to launch this default for opening the MIME label, since
- * no application is supposed to support the MIME label.
- * -the new default application is made default for all the Services & MIMEs associated with the task: for each instance
- * of CServiceMime in the list, the default is looked in the application list of the object: if it is found (which means
- * that the new default application supports that Service & MIME), then the new task default is made default for the
- * current Service & MIME too.
