[ITK] [ITK-users] Starting with GPU development

[Bradley Lowekamp]

The test may be a good starting point for some examples:

$ find  . -name "*GPU*Test.cxx"
./Modules/Core/GPUCommon/test/itkGPUImageTest.cxx
./Modules/Core/GPUCommon/test/itkGPUReductionTest.cxx
./Modules/Registration/GPUPDEDeformable/test/itkGPUDemonsRegistrationFilterTest.cxx
./Modules/Filtering/GPUThresholding/test/itkGPUBinaryThresholdImageFilterTest.cxx
./Modules/Filtering/GPUThresholding/test/itkGPUImageFilterTest.cxx
./Modules/Filtering/GPUImageFilterBase/test/itkGPUNeighborhoodOperatorImageFilterTest.cxx
./Modules/Filtering/GPUAnisotropicSmoothing/test/itkGPUGradientAnisotropicDiffusionImageFilterTest.cxx
./Modules/Filtering/GPUSmoothing/test/itkGPUMeanImageFilterTest.cxx
./Modules/Filtering/GPUSmoothing/test/itkGPUDiscreteGaussianImageFilterTest.cx
