implement SyncSlice3DVWR block #216
Description
New idea to implement subject-observer comms between modules. For now a normal
connection (later consider different type) through which an instance of the
producer module itself is passed. This can for example be used to have one
SyncSlice3dVWR module sync different elements of a number of slice3dVWRs
(coupled views).
