* @brief Define types that can be logged with Log
* @details
* As of now you can log type T with instance t:
* -# Any @ref Stringy "string-like type": eg. std::string, std::string_view
* -# Any @ref WorksWithStdToString "type that works with std::to_string()"
* -# Any @ref ExistsToString "type for which an overload of" <code>Stringy to_string(const T&)</code> exists in global or gz namespace
* -# Any @ref HasToString "type that has a to_string() const member that returns a string"
* -# Any @ref Vector2Printable "type with t.x and t.y", provided t.x and t.y satisfy one of 1-3
* -# Any @ref PairPrintable "type with t.first, t.second" provided t.first satisfies one of 1-3 and t.second satisfies 1-4
* -# Any @ref ContainerPrintable "type that has a forward_iterator" which references any one of 1-5
* -# Any @ref util::Stringy "string-like type": eg. std::string, std::string_view
* -# Any @ref util::WorksWithStdToString "type that works with std::to_string()"
* -# Any @ref util::HasToStringMember "type that has a to_string() const member that returns a string"
* -# Any @ref util::ContainerConvertibleToString "type that has a forward_iterator" which references any one of 1-3
* -# Any @ref util::PairConvertibleToString "type with t.first, t.second" provided t.first satisfies one of 1-4 and t.second satisfies 1-4
* -# Any @ref util::MapConvertibleToString "type that has a forward_iterator" which references 5
* -# Any @ref util::Vector2ConvertibleToString "type with t.x and t.y", provided t.x and t.y satisfy one of 1-6
* -# Any @ref util::Vector3ConvertibleToString "type with t.x, t.y, t.z", provided t.x, t.y, t.z satisfy one of 1-6
* -# Any @ref util::Vector4ConvertibleToString "type with t.x, t.y, t.z and t.w", provided t.x, t.y, t.z, t.w satisfy one of 1-6
* -# Any @ref ConvertibleToString "type for which an overload of" <code>util::Stringy to_string(const T&)</code> exists in global or gz namespace
*
* The higher number takes precedence in overload resolution for the log function.
*
* 1-7 include for example:
* 1-6 include for example:
* - int, float, bool...
* - std::vector<std::string>, std::list<unsigned int>
* - std::map<A, vec2<float>> if A.to_string() returns a string - ...
* - std::map<std::string, std::vector<A>> if A.to_string() returns a string - ...
