Description
At present, WorkspaceProperty cannot generally hold or return the pointer to a WorkspaceGroup because it holds that pointer (in PropertyWithValue) as the WorkspaceProperty template type. This is usually MatrixWorkspace or a subtype, and WorkspaceGroup does not subclass MatrixWorkspace. Note that this template type also plays a role in validating input workspaces.
Because of this, in order to get hold of the pointer you have to go off to the ADS. This imposes a number of restrictions on us - for example, you can't pass a group to a sub-algorithm.
We need to find a way of holding a base Workspace pointer in a WorkspaceProperty. I think that ideally this should not change the interface of WorkspaceProperty, in particular the template type as this would impact just about every single algorithm.
Turns out this is a duplicate of #6257.
