Need to describe how user can read and write nullable values using pointer semantic in Ignite C++:
{code}
// One can write null value like this:
writer.WriteObject<SomeObject*>(nullptr);
// And read it like this:
std::unique_ptr<SomeObject> nullableVal = reader.ReadObject<SomeObject*>();
if (nullableVal) {
  // Processing...
}
{code}
