+     1./ create a VirtualCpuModel that inherits from CpuModel or create
+     a VirtualCpuCas01Model that inherist from CpuCas01Model
+	  => Question: not sure which one is really usefull :( The objective is to
+     be able to create a VirtualCpu instead of a Cpu (i.e. a CpuCas01 to be exact). 
+     2. create VirtualCpu class that inherits from Cpu or create
+     a VirtualCpuCas01 class that inherits from CpuCas01 (same issue as the one described above).	
+	  Such modifications would enable us to remove the isVirtual method and
+     actually use the polymorphism feature of C++. It will also enable us 
+     to overwrite the cpu_energy hashmap in energyCpuCreateCallBack instead of invoking
+     setVirtual(). 
+     So to make a long story short, it will be cleaner from the software viewpoint 
+     and patches welcome ;) - Adrien October 20 2015
