-		-Added more parameters to log, exponential, polynomial
-		-Added SigmoidalRegKernelArthur, because Arthur apparently needs
-		to train the scaling and shifting of sigmoids
-	0.0.1:
-		-initial release, with linear, log, exponential, polynomial, and sigmoid kernels
-		-already vectorized (except for polynomial generation) and CUDA-optimized
