Realms

Realm is a Nalu abstraction of a set of equations that are solved on a computational domain, reresented by an Exodus-II mesh. A simulation can contain multiple Realms and that can interact via sierra::nalu::Transfer instance. ~sierra::nalu::InputOutputRealm is a special type of Realm that exists solely to provide data (input) or extract a subset of data from another ~sierra::nalu::Realm.
