Description
Make an empty image using the current image parameters. Often this is
unnecessary, but you will typically need to use this if you wish to
deconvolve a set of images. The steps are to make the empty images
that you require to be deconvolved, and then pass them into clean as a
vector of strings.
Arguments

Example
imgr.setimage(nx=1024,ny=1024, cellx='30marcsec',celly='30marcsec',
nchan=1, stokes='IV', phasecenter=dm.direction('mars'));
imgr.make('mars.moving');
imgr.setimage(nx=1024,ny=1024, cellx='30marcsec',celly='30marcsec',
nchan=1, stokes='IV',
phasecenter=dm.direction('j2000', '12:23:48.7', '-15:56:32.9')
imgr.make('mars.fixed');
imgr.clean(algorithm='mf', model=['mars.moving', 'mars.fixed'],
image=['mars.moving.restored', 'mars.fixed.restored'])
This makes two empty images, one moving with mars and one fixed
in j2000, and then deconvolves the two jointly using clean.
Finally the images are restored.
