/// .Binary serialization
/// Serialization is a mechanism that converts structured data to/from binary stream. In
/// U++, loading and storing of data is performed by single code, in most cases represented
/// by method `Serialize`. Serialization is performed directly with basic `Stream`. To this
/// end, `Stream` features a single boolean representing the direction of serialization
/// process. The direction can be checked using `IsLoading` and `IsStoring` methods and
/// changed with `SetStoring` and `SetLoading` methods. Direction is usually set properly
/// by derived classes (e.g. FileOut sets it to storing, FileIn to loading).
///
/// Shortcut to calling `Serialize` method is `operator%`, which is templated overload that
/// calls `Serialize` for given variable (primitive types have direct overload in `Stream` class):
