Feathering: Combine two images using the Fourier Addition:

The algorithm converts each image to the gridded visibility
plane, combines them, and reconverts them into an combined
image.  The images must have a well-defined beam shape (clean beam),
given in the image, in order for feathering to work well.
The two images must be on the same grid and have the same
flux density normalization scale.

Keyword arguments:
imagename -- Name of output feathered image
        default: none; example: imagename='orion_combined'
highres -- Name of high resolution (interferometer) image
        default: none; example: imagename='orion_vla.im'
     This image is often a clean image obtained from synthesis
        observations.
lowres -- Name of low resolution (single dish) image
        default: none; example: imagename='orion_gbt.im'
     This image is often a image from a single-dish observations
        or a clean image obtained from a lower resolution synthesis
        observations.
