inlineprotected

On periodic boundaries, the nodal area and the values to project need to take into account contributions from elements on both sides of the boundary. This is done using the conditions and the non-historical nodal data containers as follows:
1- The partition that owns the PeriodicCondition adds the values on both nodes to their non-historical containers.
2- The non-historical containers are added across processes, transmiting the right value from the condition owner to all partitions.
3- The value on all periodic nodes is replaced by the one received in step 2.
