Title: add kernel distributions: Epanechnikov, Biweight, Triweight

This adds a couple of distributions that are commonly used as kernels for kernel density estimation: see http://en.wikipedia.org/wiki/Kernel_(statistics)#Kernel_functions_in_common_use.

I'm not sure if we want these in Distributions, or if they would be better off in another package. Also, the location parameter may be unnecessary.
