+Overview:
+Declaration of message classes used by the framework for the extension
+mechanism.  Each T Class is used to pack-up data in the client thread
+and then is passed to the plugin thread where it is unpackaged.
+
+For all classes except TGetExtensionParams, the packing occurs in the
+proxy class of the extension mechanism, and unpacking in the paired stub
+class.
