This method computes the convolution function and the convolution function used for gridding the weights (typically these are the same) and returns them in the cfs and cfwts parameters.

The required information about the image and visibility parameters is dervided from the given image and VisBuffer objects. wConvSize is the number of w-term planes and pa is the Parallactic Angle in radians for which the convolution function(s) are computed.
