;*PURPOSE:
;
;	Monolook is an advanced display tool for the inspection of 3D data.
;	The display area  is divided into 3 sections:
;
;	upper:  display of the stacked spectra image
;	middle: display of monocromatic images
;	lower:  plot of spectra of certain spatial elements
;
;	The tool allows to interactively select monochromatic images
;	and the preceeding selection of spectra via mousclick on 
;	spatial pixels of the monocromatic image. 
;	You can also display the spectrum of the sum of arbitrary pixels.
;	As a consequence of that there are different sky subtraction algorithms
;	included as for example building a mean sky of selected 
;	spatial elements or a 2D-interpolation of the sky to an object
;	position. A Sky and an object spectrum as well as up to 16
;	monocromatic images can be set as output.
