    Various tools to aid synchronizing lists across coupled patches. WIP.

    - combineOperator (e.g. sumEqOp - not sumOp!) that is defined for the
      type and combineReduce(UList\<T\>, combineOperator) should be defined.
    - null value which gets overridden by any valid value.
    - transform function

    note:Can apply coordinate rotation/separation on cyclics but only for faces
38
    or if there is a single rotation/separation tensor.

    note:syncPointList or syncEdgeList will visit shared points/edges
    multiple times (once through patch exchange, once through shared
    points reduce). Should be replaced by pointMesh functionality.
