30 NAME: @code{typename_macro}, @code{pretty_typename_macro} - type demangler and pretty printer
31 DESCRIPTION:
32  These preprocessor macro-definitions are useful when dealing with complex types
33  as generated by imbricted template technics: they print in clear a complex type at run-time.
34  @code{typeid_name_macro} obtains a human readable type in a @code{std::tring} form
35  by calling the system @code{typeid} function and then a demangler.
36  When this type is very long, @code{pretty_name_macro} prints also it in a multi-line
37  form with a pretty indentation.
38 EXAMPLES:
39  @example
40  typedef map <size_t, double, less<size_t>, heap_allocator<pair<size_t,double> > > map_type;
41  cout << typeid_name_macro (map_type);
42  @end example
