 /* TODO :
+- refactor to use emit('eventname', {eventdata:'data'}) for onreleased and onpicked rather than latest element
+	e.g newEl.setAttribute("onreleased", 'document.querySelector("['+generatorName+']").emit("check",{color:"'+color+'"})')
 - insure scene setup, e.g starting position and orientation of environment and main character (until now assumed unchanged)
 - isolate emit('eventname', {test:0}) versus same with onreleased (which does NOT work) and same without event detail (which works)
 - add audio instructions

 - reset (as done for fishinbowl)
 - better menu (e.g target with onreleased)
 - fix maze/mazemap mismatch (causing emit() error on init)
 - game ideas
 	- art deco / art nouveau facade as puzzle mixed pieces
