TaskTree: Update Storage docs

Browse Source 
After recent changes, the Storage object isn't derived from
GroupItem class anymore. Instead, there is a Group constructor
taking the Storage object. Make docs precise, that Storage
isn't a GroupItem, but we may have a GroupItem containing a
Storage.

Make it clear, that the running task tree doesn't instantiate
the storage itself, but it's data type.

Add more links.
