typename_macro, pretty_typename_macro - type demangler and pretty printer
These preprocessor macro-definitions are useful when dealing with complex types as generated by imbricted template technics: they print in clear a complex type at run-time. typeid_name_macro obtains a human readable type in a std::tring form by calling the system typeid function and then a demangler. When this type is very long, pretty_name_macro prints also it in a multi-line form with a pretty indentation.
typedef map <size_t, double, less<size_t>, heap_allocator<pair<size_t,double> > > map_type;
cout << typeid_name_macro (map_type);
extern std::string typeid_name (const char* name, bool do_indent);
