Added early returns to DistanceToIn for all cases (CUDA/Scalar/Vc).
Implementation of benchmark for DistanceToIn for Vc and CUDA. CUDA is reporting incorrect numbers. Possibly a precision issue?
Fixed CUDA version, randomized biased direction generation. Ready for review!
Removed accidentally uploaded test file.
Changed implementation to not use templating for backends, but simply rely on the linking.
Mechanism for comparison of output implemented. Identical results when using doubles in CUDA!! Baby steps of Cilk implementation, but no icc yet.
