+/**
+The CSuplAsn1Decoder class provides an interface to the SUPL Protocol Module
+enabling the decoding of ASN1 encoded SUPL messages. Such messages arrive through
+either via SMS or WAP push protocols in the case of SUPL INIT messages, or via 
+a TCP/IP connection once a SUPL session has been established.
+
+The decoder provides synchronous methods for decoding received messages. Once
+Decode() has been called passing the input buffer, the buffer may be re-used as
+the decoded data is fully extracted to objects owned by the CSuplMessageBase
+derived classes.
+
+On completion of the Decode() operation, the appropriate CSuplMessageBase object
+is constructed, encapsulating the decoded message. Ownership of this object is
+passed to the calling function.
