/*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. Nodes, signals, and messages potentially have attribute values.
|
|
All of them can have comments.
