 Events in the JVM are by default timed (it's more common)
 Perhaps a little strange. Might change.
 EVENTS
 Declard with the 'event' tag.
 <value fields> can be one or more of
    value            - a simple primitive or constant type value
    structvalue      - value is a sub-struct. This type must be previously defined
                       with 'struct'
 All these require you to declare type, field and label of the field. They also accept
 an optional description of the field. If the meaning of the field is not obvious
 from the label you should provide a description. If an event however is not actually
 meant for end-users, you should probably _not_ write descriptions at all, since you
 might just add more concepts the user has no notion of/interest in.
 Events should be modeled after what conceptual process you are expressing, _NOT_
 from whatever data structures you might use inside the JVM for expressing a process.
 STRUCT
 Declared with the 'struct' tag.
 Declares a structure type that can be used in other events.
