+- SimpleAddress: A Ruby class implementing the Nuix interface Address (https://download.nuix.com/releases/desktop/stable/docs/en/scripting/api/nuix/Address.html)
+- SimpleCommunication: A Ruby class implementing the Nuix interface Communication (https://download.nuix.com/releases/desktop/stable/docs/en/scripting/api/nuix/Communication.html)

+We use these 2 classes to then build a customized communication object and ultimately provide that back to Nuix
