* \class ProjectedIterativeDeconvolutionImageFilter
* \brief Mix-in class that adds a projection step after each
* iteration.
*
* This filter follows the mix-in design pattern. When templated over
* an IterativeDeconvolutionImageFilter, this class will inherit the
* members of that filter, and it will override the definition of
* Iteration() to first call the superclass's Iteration() method
* followed by projecting all negative voxel values of each
* intermediate estimate image to 0.
*
* This code was adapted from the Insight Journal contribution:
*
* \author Cory Quammen, The University of North Carolina at Chapel Hill
*
* \ingroup ITKDeconvolution
