	* World.m (bitnamelist): Put parens around GETMA macro. Thanks to
	Thomas Badegruber for pointing out the problem and the
	fix.<[e-mail]>

	* asm.scm (cons): add D0 to all double valued entries. Windows
	users got crashes without them.

2001-11-25    <[e-mail]>

	* ASMModelSwarm.m ([ASMModelSwarm -buildObjects]): No need to set
	world or agentList in Specialist anymore.  See below where performTrading
	and completeTrading are discussed.

	* Specialist.h: changed performTrading method to performTrading:
	Market: and completeTrades is now completeTrades: Market:.  This
	way, the agent list and the market are explicitly passed in every
	time. There is no need for Specialist class to have IVARs world
	and agentList, so now the Specialist class can be archived without
	any hassle. That is, putShallow should work.

2001-11-08    <[e-mail]>

	* Output.m ([Output -writeData]): Necessary to have hdf5 archives
	putDeep because they can't save ordinary C arrays otherwise.

2001-11-06    <[e-mail]>

	* World.m (changes): Converted pricehistory and divhistory back to
	dynamically allocated arrays.  This was done because the Swarm
	archiver was writing those arrays at every timestep, massively
	filling up filespace.  Don't know how to selectively write
	variables from objects yet.

2001-11-03    <[e-mail]>

	* BFagent.m ([BFagent -initForecasts]): Now privateParams is a
	truely separate instance of BFParams, one for each object. The old
	way of using the same instance for all agents seemed fraught with
	danger.

	* BFParams.m ([BFParams -copy:aZone]): New method to create a copy
	of an instance and return it.  Does detailed copy of all ivars,
	including dynamically allocated arrays.
	([BFParams -copyProbList:p:size]): used in copy: method. This takes 
	a pointer to a double array and replaced the problist with it.
	([BFParams -copyBitList:Length:size]): copies a bitlist  and replaces
	existing bitlist with it.

2001-11-02    <[e-mail]>

	* BFParams.m ([BFParams -init]): Commented out "myWorld" array,
	couldn't find any place it was used. Also commented out
	lastgatime, couldn't figure why that value was kept here in the
	parameters object, rather than in the BFagent. Maybe there's a
	reason, but I can't find it.

	* ASMObserverSwarm.m ([ASMObserverSwarm -expostParamWrite]): fixed
	expostParamWrite error (due to unavailability of time at
	shutdown).
	([ASMObserverSwarm -buildObjects]): show probe map for BFParams
	object.

2001-11-02  Paul E. Johnson  <[e-mail]>

	* ASMObserverSwarm.m ([ASMObserverSwarm -buildObjects]): create
	IVAR output, an aOutput object. This must exist as soon as the GUI
	comes up, because the GUI buttons allow people to write
	output. So, the output has to exist before the control panel stops
	the simulation, and then the output object must be passed along to
	ASMModelSwarm, where in turn the buildObjects method sticks some
	things into the Output object.  This is at the outer limits of my
	patience.
	([ASMObserverSwarm -drop]): make sure the expostParamWrite method
	is called, to save a copy of parameters at shutdown time if
	writeParams==1;

	* Output.m ([Output -initializeHDFWriter]): Trying to stop the
	nuisance of the empty hdfGraph file that was created from runs 
	that had data writing turned off.

	* ASMObserverSwarm.m ([ASMObserverSwarm -buildObjects]): put
	control panel set state stopped before model swarm is
	created. That way, any magic done in Parameters class will be
	taken into account when the model is created.

2001-10-26  Paul E Johnson  <[e-mail]>

	* ASMModelSwarm.h: delete warmupStepDividend and warmupStepPrice.
	Delete the -initPeriod: method. It was superflous

	* ASMModelSwarm.m ([ASMModelSwarm -initPeriod:]): This method is
	unnecessary. It can be replaced by a createAction in time 0 to the
	startupSchedule.  Note memory leaks of undropped objects in the
	warmUp: method.
	([ASMModelSwarm -doWarmupStep]): new method to replace the 3
	separate methods, 

	- warmupStepDividend; 
	- warmupStepPrice;
	
	I verified that the simulation is exactly the same after this
	change.
	
	* ASMModelSwarm.h: convert warmUp and initPeriod to methods. Don't
	know why they were C functions before.  Did Autodoc documentation.

2001-10-26    <[e-mail]>

	* BFagent.h (Agent): nactive removed from IVAR list, it is used
	only in prepareForTrading, so it is defined there.

2001-10-25    <[e-mail]>

	* World.m (GETMA): GETMA(ma,i) is a macro that tells the given ma
	whether to get the exponential or regular ma. IT gets it from the
	i'th element of the array of moving averages.

	* World.h (SwarmObject): delete awieght, bweight. That gets taken
	care of byMovingAverage now. priceMA, divMA, oldpriceMA, olddivMA
	objects now replace old mas.  These MA objects keep both regular and
	exponential MAs, and retrieve them with getMA and getEWMA.

2001-10-25    <[e-mail]>

	* World.m: Moved define NMAS into World.h, converted pointers to
	arrays[NMAS], got rid of alloc's in World.m.
	
	* World.m: Moved define UPDOWNLOOKBACK into World.h,
	converted pointers to arrays[NMAS], got rid of alloc's in World.m.


2001-10-25  Paul E Johnson  <[e-mail]>

	* BFagent.m ([BFagent -CopyRule:to:from]): minstrength has to be
	put back in as a global variable because it is used in the
	performGA as well as CopyRule methods.  Changing it to a local
	variable broke CopyRule for some forecasts in which Count=0.  That
	was hard to track down, I'll tell ya.

2001-10-24  Paul E Johnson  <[e-mail]>

	* ASMObserverSwarm.hm (GUISwarm): Found way to make histograms
	work without using these IVARS *position, *wealth,and
	*relativeWealth. That means no more need for calloc calls in the
	"m" file and it also means that this model should respond well if
	agents are removed or added (i.e., numagents need not be a
	constant).

	* Output.m ([Output -writeData]): hdfWriter is an EZGraph that
	does not show on the screen, but it dumps its time series into a
	file.  That means there are 3 data outputs: 1 text, 1 archiver
	dump (either hdf5 or scm) and 1 hdf5.  This new EZGraph writer
	requires a newish edition of swarm.

2001-10-23    <[e-mail]>

	* ASMObserverSwarm.h (GUISwarm): Convert volumeGraph to EZGraph
	format, insert _volumeGraphDeath_ method for destroy notification.

2001-10-23  Paul E Johnson  <[e-mail]>

	* ASMObserverSwarm.m ([ASMObserverSwarm -buildObjects]): Convert
	Graph to EZGraphs, create _priceGraphDeath_: method for destroy
	notification.

2001-06-29  Paul E. Johnson  <[e-mail]>

	* BFParams.m ([BFParams -createEnd]): init method name changed to
	createEnd, so that these settings are ready from the moment the
	object is created.

	* Output.hm (SwarmObject): new dataArchiver object, writes in hdf5
	or lisp, according to cpp flag.

	* Parameters.h: New class to collect up parameter creation

	* Output.m ([Output -createEnd]): create timeString variable to
	capture current time. Purify it. Use it in naming files

2001-06-28  Paul E. Johnson  <[e-mail]>

	* ASMObserverSwarm.m ([ASMObserverSwarm -buildObjects]): fix
	coding for graphs to unrwap object creation because Swarm no
	longer returns values from creating methods.

2001-02-08  Paul E Johnson  <[e-mail]>

	* Specialist.[hm]: removed setEtaMax/setEtaMin methods because
	they were never used. Cleaned out unused variables.

	* Specialist.[hm]: removed init method, because its work has been 
	reallocated to other methods.

	* ASMObserverSwarm.m ([ASMObserverSwarm -expostParamWrite]): If
	writeParams is YES at the end of the run, it dumps a copy of the
	settings.  That way, there will always be a record of the
	simulation, even if the user punches the "writeSimulationParams"
	button only at the very beginning.

	* Output.m ([Output -writeParams:BFAgent:Time:t]): Moved all
	archiver-creating code and parmeter writing activity in here.

	* ASMObserverSwarm.m ([ASMObserverSwarm -writeSimulationParams]):
	Whenever you punch the "writeSimulationParams" button, it tells
	Output object to dump out a time-keyed set of parameters to
	asm.scm.  Note: If user does this before the model has started,
	nothing happens because there are no objects to save yet.  But it
	will turn on a switch that causes params to be automatically saved
	at the end of the run.

	* ASMModelSwarm.m ([ASMModelSwarm -createEnd]): added, set
	modelTime=0;
