+ *  Layout metrics utility for measuring text visuals. Measuring is
+ *  is done based on text style or font id. Mesuring texts that has been 
+ *  defined using font specification are not yet supported.
+ *  
+ *
+ *  Example of use:
+ *  
+ *  void CHelloWorldAppUi::ConstructL()
+ *     {
+ *     iEnv = CAlfEnv::NewL();
+ *  #ifdef __DEBUG
+ *     // Enable layout metrics utility visual automarking in debug builds.
+ *     iEnv->LayoutMetricsUtility()->EnableAutoMarking(); 
+ *  #endif
+ *     ...
+ *     ...
+ *     // Create some textvisuals, these will be automatically included
+ *     // into metrics reports. 
+ *     iTextVisual = CAlfTextVisual::AddNewL(*this, iLayout);
+ *     iTextVisual->SetText(KMyText);
+ *     iTextVisual->SetStyle(EAlfTextStyleSmall);
+ *     ...
+ *     ...
+ *     }
+ *
+ *   // handle any menu commands
+ *  void CHelloWorldAppUi::HandleCommandL(TInt aCommand)
+ *     {
+ *     switch(aCommand)
+ *         {
+ *         case EHellowWorldCmdMeasureVisuals:
+ *             {
+ *             // Measure currently visible text visuals
+ *             iEnv->LayoutMetricsUtility()->MeasureVisuals();
+ *             // Write a metrics report into a file 
+ *             iEnv->LayoutMetricsUtility()->WriteReport();
+ *             break;
