/**
 * A ModuleComponentRepository that wraps another, but assumes that _all_ access is local. This means that the accessor returned
 * by {@link #getLocalAccess()} will attempt both local _and_ remote access operations on the delegate.
 *
 * This is used to wrap a file-backed ExternalResourceRepository instance, so that both 'local' and 'remote' operations will
 * be considered local.
