/** The Message class and derived classes are used to pass messages between

modules. Messages are passed between modules using the message queues

(see MessageQueue class). Derived classes may add their own fields.

This base class defines two common fields: type, which is the type of

This base class defines a common type field, which is the type of

the message, and key which is a key value whose meaning is defined by

the message.

the derived class. The MessageQueue class provides methods for finding

messages by both type and key.

The Message class also provides previous and next pointers which are

used to place the messages on a queue by the MessageQueue class.
