Hi Bili,

This is awesome, and I am really impressed you've already issued a PR
with an implementation along with a YTEP.  I think your plan sounds
good, and I will provide feedback on both the PR and the YTEP.  I
think this type of thing is going to be very useful.

I’m thinking about adding more kernel functions, providing the possibility to choose from them and also the possibility for the users to provide their own ones. In my own research, a quintic spline kernel is used, for example. So I guess this functionality might also be useful for other users.
