regrid an image onto a template image

        imregrid: regrid an image to a new coordinate system.

        The new coordinate system is defined by the template parameter,
        which can be:
          * a recognized reference code string (see below),
          * a {'csys': csys_record, 'shap': shape} dictionary,
          * 'get', which does not regrid but returns the template dictionary
            for imagename, suitable for modification and reuse, or
          * the name of an image to get the coordinate system and shape
            from.  The input and template images must have the same
            coordinate structure.

        Keyword arguments:
        imagename -- Name of the image that needs to be regridded
                default: none; example: imagename='orion.image'
        template -- Dictionary, reference code, or imagename defining the new
                shape and coordinate system, or 'get' to return the template
                dictionary for imagename.  Recognized reference codes are:
                'J2000', 'B1950', 'B1950_VLA', 'GALACTIC', 'HADEC', 'AZEL',
                'AZELSW', 'AZELNE', 'ECLIPTIC', 'MECLIPTIC', 'TECLIPTIC',
                and 'SUPERGAL'.
                default: 'get'; example: template='orion_j2000.im'
        output -- Name for the regridded image
                default: imagename + '.regridded'; example: imagename='orion_shifted.im'
        async -- Run task in a separate process (return CASA prompt)
                default: False; example: async=True
