/**
 A parameter class intended to hold the information needed to identify utility 
 plugins which are to be loaded into the Utility Server. These DLLs  must have 
 @c KSsmUtilityPluginDllTypeUid as their second UID and must have a function 
 that returns an @c MSsmUtility object.
 
 The first member of this class, filename, is mandatory to identify the plugin DLL. 
 The second member is supposed to point at the DLL ordinal function which 
 instantiates and returns an @c MSsmUtility object. The prototype for this function
 must be MSsmUtility* NewL(void)
 The third member can be used for an optional validation of the third UID of the DLL.
