   * Make dirac-delta impulse response filter for convolving with the high-resolution image
  The operator A should represent the characteristics of the measurement device as it
  takes measurements at lower resolutions.  For example, in MRI as resolution is decreased,
  larger anatomical regions are included in each measurement, thus giving a
  smoother image as if the high resolution image were passed through a low-pass-filter.
  p_image below represents the smoothing convolution filter that is applied to a
  high-resolution image to best represent the low-resolution image sampling.
  In the case of no downsampling p_image is simply a perfect dirac-delta function.
  Convolution in the spatial-domain is multiplication in the frequency domain.

  In the case were some downsampling is present between the lowresolution and
  the highresolution images, we need the operator A to represent a low-pass filter
  that optimally models the lower sampling rate.  The low-pass filter is accomplished
  in the frequency domain by zeroing-out frequency components that are not representable
  in the frequency domain of the low-resolution image.

OPWEIGHTEDL2: Solves weighted L2 regularized inverse problems.
Minimizes the cost function

Inputs:  A = function handle representing the forward

         At = function handle representing the backwards model/
              the transpose of the measurment operator.
              (e.g. if A is a downsampling, At is a upsampling)
         b_FC =  a vector of measurements; should match the

         lambda = regularization parameter that balances data fidelity
              and smoothness. set lambda high for more smoothing.
