/**
 * A pairing of a {@link MsgPackSerializer} and {@link MsgPackParser} into a single class with convenience read/write methods.
 *
 * 
 * 	The general idea is to combine a single serializer and parser inside a simplified API for reading and writing POJOs.
 *
 * 
Examples:
 * 
 * 	// Using instance.
 * 	MsgPack msgPack = new MsgPack();
 * 	MyPojo myPojo = msgPack.read(bytes, MyPojo.class);
 * 	byte[] bytes = msgPack.write(myPojo);
 * 
 * 
 *	// Using DEFAULT instance.
 * 	MyPojo myPojo = MsgPack.DEFAULT.read(bytes, MyPojo.class);
 * 	byte[] bytes = MsgPack.DEFAULT.write(myPojo);
 * 
 *
 * See Also:

 * 	Marshallers
