Description

This class is a wrapper that pretends to work exactly like stl_type_index, but does not require RTTI support. For description of functions see type_index_facade.

This class on C++14 compatible compilers has following functions marked as constexpr:

default constructor
copy constructors and assignemnt operations
class methods: name(), before(const ctti_type_index& rhs), equal(const ctti_type_index& rhs)
static methods type_id<T>(), type_id_with_cvr<T>()
comparison operators

This class produces slightly longer type names, so consider using stl_type_index in situations when typeid() is working.
