* As of now you can log type T with instance t:
* -# 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::WorksWithStdToString "type that works with std::toString()"
* -# Any @ref util::HasToStringMember "type that has a toString() 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
* -# Any @ref ConvertibleToString "type for which an overload of" <code>util::Stringy toString(const T&)</code> exists in global or gz namespace
*
* The higher number takes precedence in overload resolution for the log function.
*
* 1-6 include for example:
* - int, float, bool...
* - std::vector<std::string>, std::list<unsigned int>
* - std::map<std::string, std::vector<A>> if A.to_string() returns a string - ...
* - std::map<std::string, std::vector<A>> if A.toString() returns a string - ...

* If you want your custom data type to be logable, it easiest to provide a member function with this signature:
* @code
* public:
* std::string to_string() const;
* std::string toString() const;
* @endcode
* Alternatively, or if the type is not a class overload <code> std::string to_string(const T& t) </code> in global or gz namespace.
* Alternatively, or if the type is not a class overload <code> std::string toString(const T& t) </code> in global or gz namespace.

* @subsection log_threads Thread safety
* Log can use a static mutex for thread safety. To use this feature, you have to #define LOG_MULTITHREAD at the top of log.hpp.
