Flaws in architecture.

[vdualb]

• SparkCL.Memory suggests similar functionality to Memory class interface of opencl.hpp, while it's rather a wrapper around Buffer.
• OCLHelper is written under assumption that Buffer and Memory Object are exactly the same thing.
• Command Queue properties are hardcoded
• OCLHelper.FromFilename should reside inside SparkCL. It at least should accept options.
• NDRange should probably accept other integer types
