* Generic (and simple/primitive) struct for storing a history of assignments/relations
* of workspace data to non-workspace data in a listbase inside the workspace.
*
* Using this we can restore the old state of a workspace if the user switches back to it.
*
* Usage
* =====
* When activating a workspace, it should activate the screen-layout that was active in that
* workspace before *in this window*.
* More concretely:
* * There are two windows, win1 and win2.
* * Both show workspace ws1, but both also had workspace ws2 activated at some point before.
* * Last time ws2 was active in win1, screen-layout sl1 was activated.
* * Last time ws2 was active in win2, screen-layout sl2 was activated.
* * When changing from ws1 to ws2 in win1, screen-layout sl1 should be activated again.
* * When changing from ws1 to ws2 in win2, screen-layout sl2 should be activated again.
* So that means we have to store the active screen-layout in a per workspace, per window
* relation. This struct is used to store an active screen-layout for each window within the
* workspace.
* To find the screen-layout to activate for this window-workspace combination, simply lookup
* the WorkSpaceDataRelation with the workspace-hook of the window set as parent.
*/
