Registers this element of a parallel component with the local Observer parallel component for each triggered observation.
This tells the Observer to expect data from this component, as well as whether each observation is a Reduction or Volume observation. Should be added to the phase dependent action list of the components that contribute data for volume and reduction observations.
When this struct is used as an action, the apply function will perform the registration with observers. However, this struct also offers the static member functions perform_registration and perform_deregistration that are needed for either registering when an element is added to a core outside of initialization or deregistering when an element is being eliminated from a core. The use of separate functions is necessary to provide an interface usable outside of iterable actions, e.g. in specialized pup functions.
