Running instructions
(See this 
You may run the FORWARD codes from command line i.e. 

		 IDL>for_drive 

	(see $FORWARD_DOCS/EXAMPLES).

Or you can now use the widget interface: 

		 IDL>for_widget

	There are generally three widgets: TOP (upper left), MODEL (lower left), and OPTIONS (upper right).
	Help is available via a tab on each widget (TOP HELP, MODEL HELP, and OPTIONS HELP).

Models are called as argument of "for_drive" command, e.g.,

        	IDL>for_drive,"giblow",keyword=keyword....

	or via the second button in the TOP widget.

	Model parameters are keywords. They are changed via the MODEL widget.

Observables are called via keywords, e.g.,

                IDL>for_drive,inst='aia',line=193

        or via the third button in the TOP widget
	[Additional controls sometimes available in the OBS- tab of the OPTIONS widget 
	and SPEC tab to its right.]

Physical diagnostics are called via keywords, e.g.,

                IDL>for_drive,line='dens'

        or via the fourth button in the TOP widget

Data FITS files can or put into FORWARD format from command line using routine for_plotfits, e.g.,

               IDL>for_plotfits,filename='yourlocalfilename.fits'
			or
               IDL>for_plotfits,inst='AIA',line='195',date='2013-03-05'

        or via the first button in the TOP widget (enabling easy model-data comparison when MOREPLOTS or NOERASE 
	option is chosen in Output tab).

Fields of view are available in a range of types and sizes, controlled via keywords, e.g.,

        	IDL>for_drive,gridtype='PlaneOfSky',ngrid=512.

	or via the FOV- tab in the OPTIONS widget

Line of sight integration and viewer position also can be adjusted through keywords, e.g.,

        	IDL>for_drive,cmer=-90.,nlos=100.

        or via the LOS- tab in the OPTIONS widget
	[Reducing to plane-of-sky integrated slice is allowed via the OBS- tab of the OPTIONS widget]

Settings are controlled by keywords, e.g.,

        	IDL>for_drive,readmap="nameofsavemap.sav".

        or via the fifth and sixth button in the TOP widget

Outputs are controlled by keywords, e.g.,

        	IDL>for_drive,/savemap,mapname="nameofsavemap.sav".

        or via the second button, bottom row of the TOP widget

Plots are controlled by keywords, e.g.,

        	IDL>for_drive,/plotlog,title='my favorite plot'.

        or via the PLOT- tab and DOCONT and (sometimes) FIELDLINES and STKLINES tabs to its right in the OPTIONS widget.
        Also sometimes DONOISE tab to its left.
