Reader and Writer

This two classes are helper classes, meaning that they where created to be used internally. Does that mean that you can't use them in your program? No, of course you can!

Reader

The Reader class allows you to deserialize C++ data types, so if you want to deserialize an int from a pointer, you can just do:

int result = Cereal::Reader::readBytes<int>(pointer, offset);

Writer

The Writer class allow you to serialize C++ data types, so if you want to write a float to an address, you can call Cereal::Writer::writeBytes<dataType>(pointer, offset, data):

offset = Cereal::Writer::writeBytes<float>(pointer, offset, 7.2f);

As you can see, the writeBytes function returns the new offset (in this case, 4 bytes ahead), so you can use that in a for or while loop to serialize a lot of data.
