/*classes to encapsulate data from a DBC file. Really, the stuff of interest
are the nodes, messages, signals, attributes, and comments.
These things sort of form a hierarchy. Nodes send and receive messages.
Messages are comprised of signals. Signals and messages have attributes.
Messages are comprised of signals. Nodes, signals, and messages potentially have attribute values.
All of them can have comments.
