;
;*INPUT:
;
;	array:		2D raw image
;	traces:		tracemask, i.e. 2D image, each row contains the 
;			y positions of the spectra traces in the raw image.

;*PURPOSE:
;
;	trace inspector is a viewer tool to compare a tracemask with the 
;	real positions the spectra traces in a raw spectra image.
;	A cut through the image in crossdispersion direction is plotted
;	for a selectable column and the tracemask is overplotted.
