// The MessageHeader class is used to receive and parse general headers
// to prepare for recieving body data. The class is currently just the alias
// of MessageBase class. Please refer igtlMessageBase.h for more details and
// the implementation of the class.
//
// The following is the typical unpacking (deserialization) prcedures
// using igtl::MessssageHeader class:
//
// // Create instance and set Device Name
// igtl::MessageBase::Pointer headerMsg;
// headerMsg = igtl::MessageBase::New();
//
// // Initialize receive buffer
// // Set up memory area to and receive the general header and unpack
// headerMsg->InitPack();
//
// socket->Receive(headerMsg->GetPackPointer(), headerMsg->GetPackSize());
// headerMsg->Unpack();
//
// // Check data type string
// if (strcmp(headerMsg->GetDeviceType(), "TRANSFORM"))
// {
// igtl::TransformMessage::Pointer transMsg;
// transMsg = igtl::TransformMessage::New();
// transMsg->SetMessageHeader(headerMsg);
// transMsg->AllocatePack();
//
// // Receive transform data from the socket//
// socket->Receive(transMsg->GetPackBodyPointer(), transMsg->GetPackBodySize());
//
// // Deserialize the transform data
// transMsg->Unpack();
//
// // Retrive the transform data
// igtl::Matrix4x4 matrix;
// transMsg->GetMatrix(matrix);
//
// ....
//
// }
// else if (strcmp(headerMsg->GetDeviceType(), "IMAGE"))
// {
// igtl::ImageMessage::Pointer imageMsg;
// imageMsg = igtl::ImageMessage::New();
// transMsg->SetMessageHeader(headerMsg);
// imageMsg->AllocatePack();
// socket->Receive(imageMsg->GetPackBodyPointer(), imageMsg->GetPackBodySize());
// imageMsg->Unpack();
// }
// else if (...)
