Subject: [PATCH] + added utils containing uuid generator # moved a box
generation into scenario model, since each scenario is to have its own a box
+ added JSON-LD formatting to scenario and unit model TODO: relations are
missing! --> must match with t box # ContextInformation: getJSONLD() now
returns object instead of array # (temporarily) changed showSaveScenario() so
that a box is downloaded instead of scenario JSON
