/** @file test-element-access.hpp
 ** Generic building block in the Lumiera GUI model.
 ** A model::Element has a unique identifier, which is tied to the
 ** identification scheme used in the "real" model in Proc-Layer.
 ** Model elements can be addressed receive mutations caused by changes
 ** and rebuilding of elements within the Session; moreover, a generic
 ** representation of attributes is provided.
 ** 
 ** @note as of 1/2015 this is a first draft and WIP-WIP-WIP
