+Indicate that a computation should be performed using the CPU in multi-process mode.
+Processes should be added with addprocs() or julia started with `julia -p N`.
+Processes must communicate using distributed memory operations such as remote refrences.
+Optionally pass in an object specifying algorithmic settings.

+# Examples:
+```julia
+filter(CPUProcesses(), image, kernel)
+filter(CPUProcesses(TileSize(64,8)), image, kernel)
