ToString

During logging, the SA::ToString (and SA::ToWString) function is automatically called to log any variable.
For custom class types, by default, a binary conversion string will be logged:

namespace MyNamespace
{
    class MyClass
    {
    public:
        int i = 0;
    };
}

// main.cpp
MyNamespace::MyClass m1{ 72 };
SA_LOG(m1);

[18:43:59] {Normal - Default}   main.cpp:54 - int main()
Msg:    <00-00-00-48>

By adding the SA::ToString (or SA::ToWString) specialization for a class type, the new implementation will be called instead.
The SA::ToString specialization must be included before calling the SA_LOG macro.

namespace SA
{
    // Must be defined in SA::
    template <>
    std::string ToString(const MyNamespace::MyClass& _m)
    {
        return "MyNamespace::MyClass: " + std::to_string(_m.i);
    }
}

[18:42:12][0] {Normal - Default}   main.cpp:55 - int main()
Msg:    MyNamespace::MyClass: 72

See main.cpp for a complete example.
