			 AOP -- New features

=======================================================================

Three valued logic of belief (T, F, U).  Things are initially unknown.

Successfully commits as a result of a commit rule firing when a
request message is sent.

Asynchronous running (puts an * in front of the prompt)

Changed PRIVATE ACTIONS so the text of the function is not
passed--just a named call.  No more "agent automatically passed".

Drastically improved print functions associated with commands to the
<AGENT> prompt.

Fixed so a commitment now gets retracted at the moment it is
performed.  Problem--what to do when this is the same moment it was
committed?  We lose the fact that we were ever committed, since the
negation overwrites it (same time, so F fact-status record takes
precedence.


=======================================================================

		      QUESTIONS to ask AOP group

=======================================================================

Does an "if" get tested at the time of the action contained within it?
Should IF actions perhaps have a time associated with them?
(for now, it gets tested at the time of reciept of the message)

Worry about ~CMT(a,b,phi) = B(a,~CMT(a,b,phi))!  This is now broken
	because of the new "unknown".

Problem--We lose the fact that we were ever committed when the
commitment is performed (and thus retracted) at the same *now* the
commitment was asserted, since the negation overwrites it (same time,
so F fact-status record takes precedence.


=======================================================================

			     AOP -- To Do

=======================================================================

Fix so times and agents get bound with bdg-list when committing.

Improve error handling.

Fix private actions so you can use "me" or something when you actually
want to pass the agent.

Write Lisp parser for whole agent programs so they don't need to use
  paren at all.
Write preparser for the old "Prolog form"
Allow a global *prolog-mode* to specify format for display and parsing
  of AOP statements.
Allow individual agent programs to be in either form--specify a flag
  on the first line of the file?

Fix simulation of global timegrain.

Fix "now" so it always evals to the time of the start of the most
recent tick (I think this is what we want...).

Allow "unstate" to remove fact-info records.
