Interface that allows to implement custom serialization
logic for binary objects. IgniteObject is not required
to implement this interface, in which case Ignite will automatically
serialize binary objects using reflection.
This interface, in a way, is analogous to Externalizable
interface, which allows users to override default serialization logic,
usually for performance reasons. The only difference here is that binary
serialization is already very fast and implementing custom serialization
logic for binary does not provide significant performance gains.
