+/**
+Defines a general purpose class for containing, accessing, and manipulating 
+a reference to any MMTPType derived data type. The data type buffer itself 
+resides on the heap and is managed by this class.
+
+By default all MTP simple (signed and unsigned integer), array (signed and 
+unsigned integer), and string types are supported. Support for any other data 
+types can be provided by derived subclasses which provide suitable 
+implementions of the CreateL and Destroy methods.
+
+This class and it's derived subclasses can be freely contained as member 
+variables within any CBase derived class (typically a CMTPTypeCompoundBase 
+derived class). When used as a stack variable the class's CleanupClosePushL
+method should always be used to ensure that the heap storage managed by the 
+class is correctly deallocated.
