+/* This is a largely generic activity written to test cancelling behaviour of another (typically 
+ * production code) activity. In this case it is put on top of and to test the TBindTo 
+ * activity, by the virtue of awaiting TCFDataClient::TBindTo. In principle though it can be put on
+ * top of any other activity by awaiting for something else instead. CancelTestBindToActivity hijacks
+ * and stores the original request (in this case TCFDataClient::TBindTo). It then goes to perform a 
+ * loop:
+ * { 
+ * - It forwards the stored request to the overriden activity (in this case the TBindTo activity), 
+ * - then follows it with a TCancel 
+ * - and awaits for TError. 
+ * }
+ * Each loop will send the TCancel slightly later, i.e.: at consecutive ticks triggered by messages 
+ * received by the local node (and subsequently resulting in AMMNodeBase::SignalActivities). 
+ * If you examine CActivityCancelTest::TProgressiveCancel you will see that it is blocked 
+ * (as any other synchronised activity) against gradually increasing number of ticks. It has been
+ * pointed out that the tick resolution may be too small - i.e.: that we may want to tick the
+ * activity with every message sent within the local thread (and thus with every even that can
+ * change the state of the activity peers). This can be done by signalling CActivityCancelTest
+ * from the transport upon every dispatch (or post). This is so far not done. Instead CancelTestBindToActivity
+ * is put against every mm node performing bind to (CPR and SCPR).
