def task_makemask.regridmask	(		inputmask,
			template,
			outputmask,
			axes = [3,
			method = 'linear',
			chanrange = None
	)

Regrid input mask (image) to output mask using a template.
Currently the template must be a CASA image.
The default interpolation method is set to 'linear' (since 'nearest'
sometime fails).
