Modified client code to include CasReference ids in listener entityProcessComplete() callbacks. This facilitates correlation of replies with requests, especially while handling exceptions. Application may cache a CasReference id returned from the sendCas() and correlate it with a reply received via callback. In entityProcessComplete() method the application must test if the second parameter is of type UimaASProcessStatus and if so may typecast the parameter to fetch the CasReferenceId associated with the reply msg.

> When using the UIMA-AS client 'sendCAS' api a unique ID is returned but there is no explanation of how this may be used.  When an error is returned to the UimaASStatusCallbackListener there does not appear to be a way to tell from the EntityProcessStatus which of the input CASes failed.  Since they are sent asynchronously they and their errors may be returned out of order.
