/** @file element.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
** @todo WIP ///////////////////////TICKET #959
