//! Abstract base class for all ROS Messages Types. This class defines a basic interface
//! every class must fullfill if it takes advantages of the \class ROSJsonFactory.
//! Every class must define the public typedef Group, which associates it to a message Group (\see MessageGroups). The Group type
//! is used by the \class ROSJsonFactory to determine the type of the message it creates. The
//! MessageBaseClass belongs to the \struct EmptyGroup. Passing a class belonging to the \struct EmptyGroup to the
//! \class ROSJsonFactory will yield an error.
