/** \class KernelFunctionBase
* \brief Kernel used for density estimation and nonparameteric regression.
*
* This class encapsulates the smoothing kernel used for statistical density
* estimation and nonparameteric regression. The basic idea of the kernel
* approach is to weight observations by a smooth function (the kernel)
* to created a smoothed approximation.
