/**
 * Abstract interface to a Module that provides functions to access
 * different "Operation" interfaces, which are high-level APIs to
 * run complex geometry operations on engine inputs without the caller
 * needing to know about the potential dependencies (ie, the implementations 
 * can be provided by plugins, and this non-plugin module can find them for 
 * the Engine/Editor core, avoiding the no-core-dependencies-on-plugins limitation)
 * 
 * This interface is implemented by FGeometryProcessingInterfacesModule. 
 * Client code that wants access to the operations should get this interface like so:
 * 
 *		IGeometryProcessingInterfacesModule& GeomProcInterfaces = FModuleManager::Get().LoadModuleChecked<IGeometryProcessingInterfacesModule>("GeometryProcessingInterfaces");
 *
