Class LDEmitter

Implementation Note: There should not be any default listeners for change events in a client implementation. Default listeners mean a client cannot determine when there are actual application developer provided listeners. If we require default listeners, then we should add a system to allow listeners which have counts independent of the primary listener counts.
