Kernel Density Estimation class.

"Jann Ben - ETH Zurich, Switzerland -, Univariate kernel density estimation document for KDENS: Stata module for univariate kernel density estimation."

"Cranmer KS, Kernel Estimation in High-Energy Physics. Computer Physics Communications 136:198-207,2001" - e-Print Archive: hep ex/0011057.

The algorithm is briefly described in (4). A binned version is also implemented to address the performance issue due to its data size dependance.
