TaskManager

The TaskManager class stores task objects with their associated conversation IDs for an agent.
Tasks are self-contained (reusable) pieces of code that carry out some task and (optionally) return a result, can send or receive messages, and have little dependance on the agent they are executed in.
The agent must add it's tasks during initialisation.
Each task can be used to handle the messages for a particular conversation that an agent participates in. The agent can be executing many tasks.
- For example. if an agent registers with a DF on startup, one task object can be used to handle this conversation without having to store any state for other conversations - even if they have the same protocol.
Tasks can spawn child tasks.
You extend the Task class for each task you want. The important methods are:
- newTask: Initialises the given task.
- startTask: is invoked mmediately after the task has been initialised by newTask().
- done: When invoked, parent task will have the appropriate doneX() method invoked.
- forward: Sends a Message.
- handleX: as in handleInform. These methods must be overriden by your class.
- newTask: Initialises the given task, and invokes its start method
