Change the event names to:
	"import"
	"export"
	"exportAccepted"		triggered via evt.dataAccepted() function.
Transferring data is not necessarily via drag-and-drop, so generic event names make sense.

"import" reactions can check data by class type using instanceof.
If the imported data is an object, then give it a traditional global class so that instanceof can be used to identify it.
... also try to give it a "dataType" string variable in case the class isn't available.
Import data can also be a primitive data type.  (String Number Boolean)
