    // We need to ensure that the Controller Services that are added get added to the proper group.
    // This can potentially get a little bit tricky. Consider this scenario:
    // We have a Process Group G1. Within Process Group G1 is a Controller Service C1.
    // Also within G1 is a child Process Group, G2. Within G2 is a child Process Group, G3.
    // Within G3 are two child Process Groups: G4 and G5. Within each of these children,
    // we have a Processor (P1, P2) that references the Controller Service C1, defined 3 levels above.
    // Now, we create a template that encompasses only Process Groups G4 and G5. We need to ensure
    // that the Controller Service C1 is included at the 'root' of the template so that those
    // Processors within G4 and G5 both have access to the same Controller Service. This can be drawn
    // out thus:
    // 
    // G1 -- C1
    // |
    // |
    // G2
    // |
    // |
    // G3
    // |  \
    // |   \
    // G4   G5
    // |    |
    // |    |
    // P1   P2
    // 
    // Both P1 and P2 reference C1.
    // 
    // In order to accomplish this, we maintain two collections. First, we keep a Set of all Controller Services that have
    // been added. If we add a new Controller Service to the set, then we know it hasn't been added anywhere in the Snippet.
    // In that case, we determine the service's group ID. In the flow described above, if we template just groups G4 and G5,
    // then we need to include the Controller Service defined at G1. So we also keep a Map of Group ID to controller services
    // in that group. If the ParentGroupId of a Controller Service is not in our snippet, then we instead update the parent
    // ParentGroupId to be that of our highest-level process group (in this case G3, as that's where the template is created)
    // and then add the controller services to that group (NOTE: here, when we say we change the group ID and add to that group,
