;parameters
;	ydat	[INPUT; required] data to be fit
;	xdat	[INPUT] abscissae for YDAT
;		* if not given, assumeed to be lindgen(n_elements(YDAT))
;
;keywords
;	yfit	[OUTPUT] best-fit function corresponding to KORD and PFIT
;	kord	[OUTPUT] polynomial order at which minimum MDL is achieved
;	pfit	[OUTPUT] parameters for the best-fit function
;	kmin	[INPUT] minimum polynomial order to consider
;		* default is 0, corresponding to a constant
;	kmax	[INPUT] maximum polynomial order to consider
;		* default is the smaller of 10 or half the number of data points
;	verbose	[INPUT] controls chatter
;	_extra	[JUNK] here only to prevent crashing the program
