From David Callu, " bug:

Lost the functionality to find the real type pointed by a pointer.
   Ex: a osg::Node pointer point on a osg::Group, if I look for information
       on the pointer type, the introspection say it is a "osg::Node*".
       But if I want information on the pointed type,
       the introspection must return the "osg::Group".
   

   This bug come from the osgIntrospection::Value::Ptr_instance_box::ptype() function.
   In the original version, this function use the member "Instance_base *inst_"
   like this :
      typeof(*static_cast<Instance<T> *>(inst_)->_data)

   But in the new version, this function use the template argument "T":
      typeof(typename remove_pointer<T>::type)

   This is a good meta-programming use, but here we need a dynamic request.

   Moreover the "typeof" macro define in "Reflection" header accept only a type in parameter with the new version.
   


 fix:
   Add the macro "typeofvalue" in "Reflection" header which accept a value or a type in parameter.
   Restore original code in osgIntrospection::Value::Ptr_instance_box::ptype() function.
