Create a "width" x "width" Gaussian kernel with stdev "sigma".
Create an automatically-sized Gaussian kernel.
Estimate a "reasonable" odd size for kernel with "sigma".
Local version of GaussianKernel that produces a Matrix.
The standard library version of GaussianKernel is set up to produce a ScalarField. PolynomialExpansion and PolynomialKernels can't work with a Gaussian in this format, however. This local object is here to simplify porting.
