*
* This script implements the HACP messaging for AICC. The API messaging is
* made by another set of scripts.
*
* Rules for HACP processing of one AU
* Rule #1 The first HACP message issued must be a GetParam
* Rule #2 The last HACP message issued must be an ExitAU
* Rule #3 At least one PutParam message must be issued prior to an ExitAU message
* Rule #4 No HACP messages can be issued after a successfully issued ExitAU message
*
* Only suspend_data and core.lesson_location should be sent updated to a late GetParam
* request. All other params should be as when the AU was launched.
