SUPL Spoof Server

Generates ASN1 encoded SUPL messages.

Decodes and checks content of ASN1 encoded SUPL messages.

Required for testing of the SUPL Protocol Controller ASN1 library.

Messages generated by the spoof server are used for testing the

decoding of received messages. Encoding of sent messages is checked

by the decode and check methods.
