// Description: This adaptation plugin implementation is for test/reference purposes.   
// The loading of this plugin is controlled through test macro defined in the iby file "ssmcompatibility.iby".
// If the macro "TEST_SSM_MACRO" is not defined, original plugins are loaded and this plugin is not loaded.
// If the test P & S key is set in the test code, the calls are routed to the reference or dummy implementations.
// Else the actual plugins are loaded and the calls are routed to the actual implementations.
// The test P & S key which it looks for is KEmergencyCallRfAdaptationPluginPropertyKey(0x2000E657)
