Public Member Functions
	TraceCounter ()
	constructor
	~TraceCounter ()
	destructor
void	traceInit (char **argv)
	process command line arguments!
void	traceBegin ()
	turn trace on/off, note that charm will automatically call traceBegin() at the beginning of every run unless the command line option "+traceoff" is specified
void	traceEnd ()
	turn trace on/off, note that charm will automatically call traceBegin() at the beginning of every run unless the command line option "+traceoff" is specified
int	traceRegisterUserEvent (const char *userEvent)
	registers user event trace module returns int identifier
void	userEvent (int e)
	a user event has just occured
void	creation (envelope *e, int epIdx, int num=1)
	creation of message(s)
void	messageRecv (char *env, int pe)
	???
void	beginExecute (envelope *e)
	begin/end execution of a Charm++ entry point NOTE: begin/endPack and begin/endUnpack can be called in between a beginExecute and its corresponding endExecute.
void	beginExecute (int event, int msgType, int ep, int srcPe, int ml=0, CmiObjId *idx=0)
	begin/end execution of a Charm++ entry point NOTE: begin/endPack and begin/endUnpack can be called in between a beginExecute and its corresponding endExecute.
void	endExecute ()
	array idx
void	beginIdle (double curWallTime)
	begin/end idle time for this pe
void	endIdle (double curWallTime)
	begin/end idle time for this pe
void	beginPack ()
	begin/end the process of packing a message (to send)
void	endPack ()
	begin/end the process of packing a message (to send)
void	beginUnpack ()
	begin/end the process of unpacking a message (can occur before calling a entry point or during an entry point when
void	endUnpack ()
	begin/end the process of unpacking a message (can occur before calling a entry point or during an entry point when
void	enqueue (envelope *e)
	???
void	dequeue (envelope *e)
void	beginComputation ()
	begin/end of execution
void	endComputation ()
	end computation, do a reduction here in hopes that it finishes before traceClose called and the program exits
void	traceClearEps ()
	clear all data collected for entry points
void	traceWriteSts ()
	write the summary sts file for this trace
void	traceClose ()
	do any clean-up necessary for tracing

Private Member Functions
void	beginOverview ()
	start/stop the overall counting ov eps (don't write to logCount, just print to screen
void	endOverview ()
void	switchCounters ()
	switch counters by whatever switching strategy
void	registerArg (CounterArg *arg)
	add the argument parameters to the linked list of args choices
bool	matchArg (CounterArg *arg)
	see if the arg (str or code) matches any in the linked list of choices and sets arg->code to the SGI code return true if arg matches, false otherwise
void	usage ()
	print out usage argument
void	printHelp ()
	print out all arguments in the linked-list of choices
