/**

*  Profile engine interface.

*  This class offers methods to get active profile, active profile ID,

*  profile names array and set active profile.

*  How to use:

*  @code

*  // Create profile engine by using Factory:

*  MProEngEngine* profileEngine = NewEngineL();

*

*  // Free resources with MProEngEngine::Release();

*  profileEngine->Release();

*  // or if you release resources in destructor:

*  if( iEngine )

*      {

*      iEngine->Release();

*      }

*

*  // If you put this class to CleanupStack then use void CleanupReleasePushL()

*     CleanupReleasePushL( *profileEngine );

*  @endcode

*

*  @lib ProfileEngine.lib 

*  @since 3.1
