 This version of parrot_double_blur shows problem with stencil code.
pure_python vs opencl stencils now in agreement to 4 decimal places, but @fused and @dont_fuse_fusables now give different results
fixed missing initializer in archived pure vs opencl test code
Fix to operation copy logic in fusion
minor cleanup in aisle 7

one of two problems illustrated, somehow values in array get over 255.  Should not be possible because stencil is average over neighbor hood.  Seems to be related to the fact that stencils classes are re-used.  Perhaps more caching issues
Update benchmark scripts
