+/**
+Clients must implement this interface in order to instantiate objects of type 
+CRemConCoreApiTarget. This interface passes incoming commands from RemCon to 
+the client. 
+In order to minimise the number of virtual functions the client has to 
+implement, (a) they aren't pure, and (b) most commands are presented via 
+'Command' with an operation ID. 
+Commands which are associated with command-specific data come instead through 
+specific methods, e.g. 'Play', which comes with a play speed.
+Incoming commands are given to client via the MRemConCoreApiTargetObserver mixin. 
+Having received a command, the client is obliged to send a response.
+A client can only have one send outstanding at any time. 
+If commands come in quickly, the client is responsible for queueing its responses to them. 
+Note that each command delivered to a target involves memory allocated in the server’s heap, 
+which is only released on client closure or when a response is sent.
