* This class provides functions to manage backgroundjobs in ownCloud
*
* There are two kind of background jobs in ownCloud: regular tasks and
* queued tasks.
*
* Regular tasks have to be registered in appinfo.php and
* will run on a regular base. Fetching news could be a task that should run
* frequently.
*
* Queued tasks have to be registered each time you want to execute them.
* An example of the queued task would be the creation of the thumbnail. As
* soon as the user uploads a picture the gallery app registers the queued
* task "create thumbnail" and saves the path in the parameter instead of doing
* the work right away. This makes the app more responsive. As soon as the task
* is done it will be deleted from the list.
